4/34
Appellants Victor M. Alvarez and Diana Matos, com
law husband and wife, were convicted by a jury in t
District of Puerto Rico for aiding and abetting several dr
offenses.1 Miguel Flores, though not a party to t
appeal nor convicted in the same trial, played a centr
role in the alleged cocaine trafficking scheme and plea
guilty to the identical charges. Appellants defen
against the charges alleging that they were unwitti
participants in defendant Flores' cocaine trafficki
scheme. Flores offered testimony to the same end. Ea
appellant advances numerous grounds for reversal.
Appellant Alvarez appeals his convictions allegi
that the district court (1) erroneously refused to acce
defendant Flores' guilty plea prior to the trial of Alvar
and Matos, (2) improperly prohibited Flores from testifyi
that his testimony exposed him to criminal penalties f
cocaine trafficking, and (3) errored in denying appellant

1 Alvarez and Matos were convicted for the possession
cocaine with intent to distribute in violation of 18 U.S.
2 and 21 U.S.C. 841(a)(1); the importation of cocai into the customs territory of the United States in violati of 18 U.S.C. 2 and 21 U.S.C. 952(a); and the failure

motion for judgment of acquittal. We affirm with respect
Alvarez.
Appellant Matos joins the arguments of Alvarez a
further appeals her convictions, alleging that the distri
court failed to exclude government evidence that
produced in violation of Rule 16, Federal Rules of Crimin
Procedure. As to Matos, we reverse and remand to t
district court for a new trial.
I. Evidence __ ________
We recite the evidence in the light most favorab
to the prosecution. United States v. Campbell, 874 F.
__________________________
838, 839 (1st Cir. 1989). The evidence showed that
December 8, 1989, Victor M. Alvarez, Diana Matos, and Migu
A. Flores arrived at the Luis Munoz Marin Internation
Airport, San Juan, Puerto Rico, on American Airlines fli
904 from Caracas, Venezuela. A U.S. Customs Inspecto
Francis Aponte, noticed that the three individuals appear
to be nervous and were talking secretively among themselve

Inspector Aponte approached the individuals, made routi
inquiries of them, and referred the group to the seconda
inspection station (a table used to examine the contents
a passenger's luggage). At that time, appellant Alvarez

Inspector Aponte testified on cross-examination that he
not made any written record of the group's suspicio
behavior even though such information would have been
important part of the case report.
Carlos Ortiz, also a U.S. Customs Inspecto
testified that he noticed two individuals, later identifi
as Flores and Matos, pushing two carts stacked with lugga
and that he motioned for them to approach his seconda
station. Inspector Ortiz requested Matos' and Flore

customs declaration cards, noting that both cards appear
to have been filled out by the same person. Mat
complained that the airline had broken a bottle of liqu
that she packed in her suitcase. During his search of t
luggage, Ortiz noticed that the luggage contained both men
and women's clothing and he discovered a heavy, newspap
wrapped package. Ortiz unwrapped the package to find
aged painting of a young girl in a wooden frame. Ort
asked Matos if she had purchased the picture on her trip,
which she answered "yes."
Inspector Ortiz consulted with a senior inspecto
took the picture to a search room, and drilled into t

Alvarez in the airport's main concourse and placed him un
arrest. Inspectors conducted a thorough search of t
group's luggage, finding two additional paintings t
concealed cocaine and discovering false bottoms in each
the six suitcases that also concealed cocaine. Custo
agents determined that the group carried more than t
kilograms of cocaine.
A grand jury returned a three count indictment
January 3, 1990, against Matos, Alvarez, and Flores. Ea
defendant pleaded not guilty. On October 2, 1990, Flor
filed a notice to plead guilty on one count of t
indictment. It appears, however, that Flores intended
plead guilty on all three counts, and on October 5, 1990,
amended his petition accordingly. On October 5, 1990, t
district court extensively questioned Flores befo
declining to accept his plea. Flores asserted that Alvar
and Matos had been unaware of any plan to import cocaine a
that he, himself, was solely responsible for the crime. T
judge suspended the proceeding because she was unsu

whether Flores could plead guilty to aiding and abettin
crime while simultaneously proclaiming the innocence of t
other alleged participants.
On October 9, 1990, the Flores plea hearing resume
The judge explained that Flores' refusal to acknowledge t
aiding and abetting modality did not preclude his guil
plea. The court then engaged in an extensive colloquy wi
defendant Flores in accordance with Rule 11 of the Fed.
Crim. P. The judge noted that Flores had proclaimed t
innocence of Alvarez and Matos in a confidential letter t
Flores had written to the judge from prison. Flor
confirmed sending the letter and explained that appellan
were friends of his from New York, the home of all t
parties. Flores had invited appellants to join him on
cruise from San Juan to several caribbean islands, includi
a stop in Caracas, Venezuela. While on the cruise, Flor
met a man who offered him three thousand dollars to bri
several pictures from Venezuela to Puerto Rico. Flor
agreed to meet the man at a hotel in Caracas and to car
the pictures into Puerto Rico as a passenger on a commerci
airline. Flores did not tell Alvarez or Matos of
scheme.

Flores, Alvarez, and Matos left the ship while
was in port in Caracas to visit the beach. Flores clai
to have tricked the appellants into missing the ship
scheduled departure because he did not want to fly to Puer
Rico alone. After missing the ship, Flores took Alvarez a
Matos to the predesignated hotel, checked the group into t
rooms, secretly picked up the pictures, and borrowed sever
pieces of luggage from the man after explaining that t
group had left their bags on the cruise ship. Flor
arranged to meet the man in Puerto Rico at which time Flor
would deliver the pictures and return the borrowed lugga
Flores claimed that he never saw the cocaine or even kn
for certain that he was carrying cocaine,2 but "imagine
that the frames concealed cocaine because "nobody is goi

covered them with cloths. Flores maintained that appellan
were totally unaware of his trafficking scheme during t
entire trip.
The district court declined Flores' plea, stating:
Now, you have stated that you did not know whatin the picture frames, you did not know what was
any of the luggage that you carried. That in itse carries with it a defense that you could present
the jury. So I am not convinced that you have ma
a plea of guilty that I could accept that hasbasis in fact that contains all elements of t

offenses charged which is a requirement for t court to accept your plea of guilty. Among tho elements, those of knowledge and intent.
Flores then moved to sever his trial from that of t
appellants. Finding that it would be impossible to mount
adequate defense if Flores testified in favor of Alvarez a
Matos, the district court granted both the motion to se
Flores' trial and Flores' request to be tried aft
appellants.
At trial, Matos called Flores as a witness
offered essentially the same testimony as given to the ju
during his attempted plea. During examination by Alvare
Flores was permitted to testify that it was a crime to bri
cocaine into the United States, but he was not permitted
testify as to the punishment that could be imposed for
crime or as to his aborted plea attempt. The jury fou
Matos and Alvarez guilty on all charges.

One week later, Flores again came before t
district court to offer his guilty plea, but this time
admitted that he knew cocaine was concealed within t
picture frames. The court accepted his plea.
II. Alvarez's Conviction ___ ____________________
Appellant Alvarez attacks his conviction on thr
fronts. First, Alvarez alleges that his defense
prejudiced because the district court erroneously failed
accept defendant Flores' guilty plea prior to the trial
Alvarez and Matos. Alvarez claims the judge relied
"perceived technical deficiencies" with Flores' plea, rat
than crediting the weight of Flores' testimony t
indicated he accepted full responsibility for the cri
This error, Alvarez argues, prejudiced his defense becau
he was deprived of the opportunity to put Flores' guil
plea before the jury as persuasive evidence of Mr. Flore
credibility and sincerity.
We are unpersuaded by appellant's argument.
criminal defendant has no constitutional right to ple
guilty. North Carolina v. Alford, 400 U.S. 25, 38 n. __________________________
(1970) (a trial judge need not "accept eve

-
7/26/2019 United States v. Matos, 1st Cir. (1993)
14/34
constitutionally valid guilty plea merely because
defendant wishes so to plead"). Nor does Rule 11 of t
Federal Rules of Criminal Procedure create such a rig
United States v. Bednarski, 445 F.2d 364, 365-66 (1st Ci ___________________________
1971). Here, the district court conducted a prolon
hearing to determine the sufficiency of Flores' plea a
carefully considered his testimony. While Alvarez mi
reach a different conclusion than the judge as to t
factual sufficiency of Flores' attempted plea, we find
error in district court's determination.
Second, Alvarez alleges that the district cou
violated both the Compulsory Process and the Confrontati
Clauses of the Sixth Amendment by improperly limiting t
scope of Flores' testimony and, thereby, depriving t
defendants of forceful evidence of Flores' sincerity a
credibility. On direct examination, Matos asked Flore
"You have testified under oath regarding the exceptan
[sic] of a criminal offense. Are you aware of t
-
7/26/2019 United States v. Matos, 1st Cir. (1993)
15/34
punishment that could be imposed for this crime?"
The district court sustained the government
objection to the question, reasoning that Flores had n
actually pleaded guilty and that he might or might not
found guilty at a later trial. Moreover, Flores' testimo
-11-
11
would not necessarily be admissible against him in his o
trial unless he chose to testify in his own defense. T
judge did, however, allow Matos to ask Flores if he
previously asserted the appellants' innocence.
Alvarez then conducted what he termed a "cros
examination" of Flores -- a characterization rejected by t
trial court. The government argued that even though Flor
was not a joint witness of the appellants, cross-examinati
was unavailable because Flores was clearly testifying
Alvarez's favor. Though we are inclined to agree with t
trial court, we need not decide the issue because Alvarez
-
7/26/2019 United States v. Matos, 1st Cir. (1993)
16/34
Sixth Amendment objection fails regardless of how t
examination is characterized. Flores was permitted
testify on "cross-examination" that he knew it was a cri
to bring cocaine into the United States and that he
"wanted to talk about [his story] for some time."
The Confrontation Clause of the Sixth Amendme
provides that "[i]n all criminal prosecutions, the accus
shall enjoy the right . . . to be confronted with t
witnesses against him." Cross-examination, the prima
interest secured by the Confrontation Clause, is "t
principal means by which the believability of a witness a
the truth of his testimony are tested." Kentucky_________

the district court abused its discretion and committe
reversible error when it prevented the jury from learning
the exact penalties that Flores would face if convicted
cocaine trafficking. We conclude the court committed
error.
Flores was allowed to put his entire story befo
the jury, including important information that supported
-13- 13
-
7/26/2019 United States v. Matos, 1st Cir. (1993)
18/34
credibility. The jury heard Flores testify that importi
cocaine into the U.S. is a crime. We are confident that t
jury knew that a conviction for importing a large quanti
of cocaine carries a serious punishment. Though the ju
did not learn of the precise penalty imposed for dr
trafficking or that Flores had attempted to plead guilt
the decision to exclude this evidence was within t
district court's discretion. The judge could proper
conclude that such testimony might mislead or confuse t
jury; particularly where, as here, the witness sought
testify to the same penalties faced by the defendants.
We note that Sixth Amendment right of cros
examination is directed at uncovering witness bias a
untruthfulness. In this case, however, Alvarez sought
use "cross-examination" to bolster the witness' credibilit
Contrary to appellant's assertion, exposing a witness' bi
to lie can, indeed, be more important than exploring
witness' motivation for telling the truth. Cf. Fed.

Alvarez also asserts that the district cou
violated the Compulsory Process Clause of the Six
Amendment. According to Alvarez, the district cou
interfered with his constitutional right to prese

portion of Flores' testimony that weighed in favor
Flores' credibility. The Compulsory Process Clau
guarantees every criminal defendant "the right . . . to ha

We, therefore, affirm Alvarez's conviction.
III. Matos' Conviction ____ _________________
In addition to joining in the arguments advanced
Alvarez, Matos contends that her conviction must be revers
because the government presented in its case-in-chief
oral statement allegedly made by Matos which the governme
failed to disclose during pre-trial discovery as required
Fed. R. Crim. P. Rule 16. Specifically, Matos challenges
portion of the testimony given by Officer Ortiz, a U.
Customs Inspector who searched Matos' luggage. Offic
Ortiz testified that during the search he asked Matos
she had purchased the picture on her trip, to which s
answered "yes." Ortiz's testimony was the only dire
evidence that the incriminating picture belonged to Matos.
The substance of Officer Ortiz's testimony came as
surprise to Matos because she had made two prior requests
the government -- first by letter on January 11, 1990 a
second by formal motion on January 22, 1990 -- to comp
with the discovery provisions of Rule 16, including
-19-

7/26/2019 United States v. Matos, 1st Cir. (1993)
26/34
specific request for any "oral statement[s of the defendan
which the Government intends to offer in evidence at t
trial." The government responded by expressly acknowledgi
its obligations under Rule 16 and by producing sever
documents. The government, however, made no mention
Matos' alleged statement at that time or at any time befo
the damaging testimony came before the jury. During cros
examination, Officer Ortiz admitted that his prior testimo
at a preliminary hearing and before a grand jury did n
include any reference to Matos' alleged statement concerni
the picture.
The following morning, Matos moved to strike Offic
Ortiz's testimony and for the court to admonish the jury
disregard the testimony. Matos argued that prosecuti
records showed that Officer Ortiz had told the government
Matos' alleged statement in April 1990, but that t
government failed to produce the statement despite repeat
requests by Matos. The judge denied the motion witho
giving an explanation.

statement attributed to Matos was a very significant pie
of evidence that indicated Matos was a participant in t
crime, rather than merely being an innocent bystan
present at the scene of a crime. Similarly, the alle
statement fundamentally sabotaged Matos' defense that s
was an unwitting participant in Flores' cocaine trafficki

exculpated appellants.
Given the central importance of the alle

During a discussion with Matos' counsel, the ju

of the statement only the day before, that he had

judge, stated that at that time he had no grounds_____________

We are not surprised that Matos was unprepared to articula
a particular ground for suppressing the statement un
these circumstances and in the middle of a trial. The o
possible curative course, suspending the trial and holdin
suppresion hearing, was erroneously rejected by the distri
court.
The government is wholly responsible for unfair
surprising the defendant and should not benefit from its o
violation of Rule 16.
In summary, we affirm the conviction of Alvarez a
reverse and remand for a new trial as to Matos.
