Page 4: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Terminology

• Search Warrant: judge’s written order for a peace officer to search a specified place and to seize evidence

• Anticipatory—certain evidence will be found in a specific place at a given time

Page 8: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Terminology

• Doctrine of Particularity: warrant must state specifically what is to be searched

• Four Corners Rule: all information perti-nent to search warrant affidavit must be included “within the four corners of the affidavit”

Page 9: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Terminology

• Probable Cause: The facts or apparent facts that would lead a “reasonable person” to believe that a crime has been committed or that evidence of the crime could be found at a specific location

• Standing: Person must have reasonable expectation of privacy to protest an illegal search

Page 10: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Recap: Warrants and Probable Cause • Warrants are issued and arrests made if the

evidence can demonstrate probable cause. • Probable cause is defined by the Fourth

Amendment as “a necessary element of a legitimate or legal search and seizure; a reasonable ground to believe that someone is committing or has committed an offense. It must amount to more than just suspicion but need not rise to the level of evidence justifying conviction.”

Terminology

• Exclusionary Rule: Illegally obtained gambling evidence was inadmissible (Weeks v. U.S., 1914) This is a prophylactic rule—formulated by judges to protect a fundamental right.

• Fruits of the Poisonous Tree Doctrine: if illegal evidence leads to evidence that would otherwise have been legally obtained (derivative evidence), that latter evidence is also inadmissible (Silverthorne Lumber Co. v. USA, 1920)

Landmark Cases

• Mapp v. Ohio (1961) Dollree Mapp convicted of possession of obscene materials based upon fruits of illegal search (for bomb-making materials). The ruling made the Exclusionary Rule binding upon all states.

Landmark Cases

• Gideon v. Wainwright (1963) Clarence Gideon, an indigent, had been convicted of breaking into a pool hall. He asked for but was denied a court-appointed attorney. Court-appointed attorneys were appointed only in capital cases in Florida. Conviction overturned under the 6th Amendment. Gideon was subsequently acquitted at retrial.

• "It has become almost axiomatic that the great rights which are secured for all of us by the Bill of Rights are constantly tested and retested in the courts by the people who live in the bottom of society's barrel . . . ."

(Tobias Smith, Florida Civil Liberties Union, in a comment regarding Gideon)

Page 16: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Landmark Cases

• Escobedo v. Illinois (1964) Danny Escobedo questioned for murder; denied access to his attorney. Conviction reversed.

Page 17: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Landmark Cases

• Miranda v. Arizona (1966). Miranda convicted of murder; his confession was obtained without his having been apprised of his right of silence. That he had been through the system several times was insufficient evidence that he understood his 5th Amendment right. Conviction reversed (but he remained in prison).

Page 18: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Landmark Cases• Mincey v. Arizona (1978) Rufus Mincey convicted

of murder, assault, and narcotics charges based upon 4-day warrantless search, justified by “murder scene exception”. There is no murder scene exception. A warrantless search must be "strictly circumscribed by the exigencies which justify its initiation," Conviction reversed.

• The evidence seized on the basis of a mistakenly issued search warrant could be introduced at trial when it is established that the police acted in good faith on a warrant issued by a judge.

Page 29: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Illinois v. Rodriguez, 1990• Regarding third-party consent to search, it was

reasonable to conclude that the consenting party had authority over the premises, based on the facts available at the moment; thus, the evidence was admissible.

Page 30: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Nix v. Williams, 1984• The Inevitable Discovery Doctrine allows for

evidence to be used, even if it was collected illegally, if the prosecution can show that the evidence would have been discovered from a hypothetical, independent source.

Page 31: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Arizona v. Evans, 1995• A search was found to be reasonable, even though

the officer had justified the search based upon an arrest warrant—which had been canceled earlier but was erroneously still showing to be active.

Page 32: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Corpus Delecti• “Body of the crime”

Rules for Admissibility of Scientific Evidence:

More Cases…

Page 37: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Rules for Admissibility of Scientific Evidence

• To determine the admissibility of scientific evidence, there must be method validation and laboratory validation. The evidence must also be relevant to the investigation and reliable. After the case Frye v. United States, the court issued a test, called the Frye rule, for determining admissibility.

• The Frye rule states that “the principle governing admissibility is the general acceptance of the test’s underlying principles by the scientific community to which the test belongs.”

Page 38: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Frye v. United States: Summary

• http://answers.yahoo.com/question/index?qid=20100206123400AABJ4yB

• Basically, the evidence and the analysis method must have general acceptance in the scientific community.

Page 39: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Daubert v. Merrell Dow Pharmaceuticals, Inc.

• http://legal-dictionary.thefreedictionary.com/Daubert+standard

• Daubert v. Merrell Dow Pharmaceuticals:• Whether a "theory or technique . . . can be (and has been) tested"

• Whether it "has been subjected to peer review and publication".

• Whether, in respect to a particular technique, there is a high "known or potential rate of error"

• Whether there are "standards controlling the technique's operation".

Page 40: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Daubert Standard• The federal courts have since issued a set of

criteria for scientific evidence called the Daubert Standard after case William Daubert. ux. etc., et al. v. Merrell Dow Pharmaceuticals, Inc. This standard creates a more rigorous test for scientific admissibility.

Page 41: LEGAL CONSIDERATIONS IN CRIME SCENE INVESTIGATION

Frye and Daubert

• Using both the Frye rule and Daubert Standard, the federal courts have developed the Federal Rules of Evidence (FRE).

• These rules apply to federal cases only, but many states have adopted them.
