Screwdriver, Jimmy, Cutting DevicesOsterburg & Ward, 2007, p. 41

Tool Impressions

You could add any additional information or explanation here.

Examples Methods of Collection

Examination Information Contamination Issues

Examples: Hammer etc.

How would you collect package transport and store these pieces of evidence?

How would you examine this type of evidence?

What information would this evidence provide?

How might this evidence be contaminated or compromised?

Probable CauseProbable Cause Facts that a reasonable, prudent person would accept as a basis for decision

making.

Quantity Prima facie: presumptive but rebuttable. (Evidence that is sufficient to raise a presumption of fact or to establish the fact in question unless rebutted)1

Degree of Uncertainty Less than apparent but still quite possible.

Usage in Science Basis for theory development through testing of hypothesis. (A conjecture that provisionally accounts for a set of facts: can be used as the basis for additional investigation and guide in gathering further information)2

Law in the U.S. Satisfies requirement for an arrest or issuance of a warrant for search and seizure of evidence.Basis for going on to the next stage of a legal proceeding.

If no defense is made, prima facie evidence forevery element constitutes a prima facie case that is sufficient to support a conviction in criminal cases.

Criminal Investigation in the U.S.

Obtain a search warrant what or an arrest warrant.

(Accessed 12/18/08)

The end product of a process that starts with the first-responding officer’s report that is processed by data entry personnel, entered into a database, and transformed into a symbol on paper. In this narrow interpretation, a map is merely a picture or part of a database.

Confidential Source

Any individual stipulating confidentiality, who is freely providing intelligence or investigative information on a “one-time” basis, or responding to questions during a field interview, or in a custody interview.

Reliable Confidential Informant (RCI): A confidential informant who has furnished information in two separate matters, is found to be reliable through independent sources and investigation and has satisfactorily fulfilled all other criteria. http://tallahassee.com/assets/pdf/CD10811059.PDF (Accessed 12/18/08)

Probable Cause

Apparent facts discovered through logical inquiry that would lead a reasonably intelligent and prudent person to believe that an accused person has committed a crime, thereby warranting his or her prosecution, or that a Cause of Action has accrued, justifying a civil lawsuit.

The probable cause standard is more important in Criminal Law than it is in Civil Law because it is used in criminal law as a basis for searching and arresting persons and depriving them of their liberty. Civil cases can deprive a person of property, but they cannot deprive a person of liberty. http://legal-dictionary.thefreedictionary.com/Probable+Cause (Accessed 12/18/08)

Quid Pro Quo

Something for something, as in making a deal, e.g., plea bargaining (Osterburg & Ward, 2007, p. 800).

QUID PRO QUO - Lat. 'what for what' or 'something for something.' The concept of getting something of value in return for giving something of value. For a contract to be binding, it usually must involve the exchange of something of value. http://lectlaw2.securesites.net/def2/q003.htm (Accessed 12/18/08)

When to cite?

Whenever you are referring to an idea that is not uniquely your own, one that has been drawn from another source, you must “cite” that idea as someone else’s. The most common example is from a periodical or book: Criminal investigation must be conducted

within the framework of our democratic system (Osterburg & Ward, 2007).

When to cite?

The citation follows the expression of the idea; typically at the end of a sentence (an exception would be when you express two or more ideas in one sentence: Community policing involves developing

a relationship between citizens and the police department (Jones, 2005).

This is the citation

When to cite?

The order of the citation is important, and should include, in parenthesis, the author’s name, a comma, and the year of publication: Community policing involves developing

a relationship between citizens and the police department (Jones, 2005).

Author name Year

When to cite?

You must cite the particular book each time you draw from it; not just the first time you use it in a text.

When to cite?

If your citation refers to a specific page or pages, you should also include that in your citation: Motive is an important factor in pointing to

possible suspects in a homicide. Often there is a personal relationship between victim and perpetrator that, if subjected to stress may impel one of them to kill the other. (Osterburg & Ward, 2007, p. 355).

Page number

When to cite?

Important: if you directly quote a text, you must put the quote in quotation marks: “Community policing involves

developing a relationship between citizens and the police department” according to one source (Jones, 2005, p. 48).Note the blue portion is a direct quote from

the Jones source

When to cite?

As mentioned earlier, you might have two ideas from two different sources (notice the placement of the first citation after the first idea): Community policing involves developing

a relationship between citizens and the police department (Jones, 2005, p. 48) as well as teaching citizens how to handle their own crime problems (Smith, 1998). 2nd “idea”

When to cite?

Almost without exception, your in-text citation should “connect” to an entry in your reference list toward the end of your paper. Reference list formats are covered later: Anyone who discloses investigative

information can be considered an informant. (Osterburg & Ward, 2007, p. 233).Osterburg J. & Ward R., (2007). Criminal Investigation:

A Method for Reconstructing the Past. (5th Ed)Newark, NJ: Matthew Bender & Company

Reference list

When to cite?

You may also at times refer to works without the parenthesis, if it “flows” better with your paper: Jones has stated that community

policing involves developing a relationship between citizens and the police department (2005, p. 48).

Note the author is left out because it

was mentioned earlierin the sentence

When to cite?

Here is another example of not using parenthesis: In 1998, Jones reported that community

policing involves developing a relationship between citizens and the police department (p. 48).

In this instance the author and the year are mentioned in the prior sentence. The page number (specific to the idea) is the only citation listing. If you are referring to the entire work’s

idea, you might not even have the page number in parenthesis.

Examples: No authors

What if your source does not have an author listed anywhere? You will list the first few words of the title of the work: Community policing involves developing

a relationship between citizens and the police department (“Policing in Action”, 2005).

Title synopsis

Examples: No date

What if your source does not have a publish date listed anywhere? You will list the author, and “n.d.” for “no date”: Community policing involves developing

a relationship between citizens and the police department (Jones, n.d.).

n.d. = “no date”Note: if you don’t have an

author or a date, your citationmight read:

(“Policing in Action”, n.d.)

Examples: Two authors

Your book or periodical might have more than one author. You must list both authors every time you draw and idea from that particular source: Community policing involves developing

a relationship between citizens and the police department (Jones & Smith, 2005, p. 48).

2nd Author

Examples: Three to Six Authors If you have three to six authors, you cite two

different ways. The first time you cite the source, you list all authors: Community policing involves developing a

relationship between citizens and the police department (Jones, Smith, & White, 2005).

Each additional time you cite this source in your paper, you only list the first author, and follow it up with “et al.”: Community policing involves developing a

relationship between citizens and the police department (Jones, et al.).

“et al.” stands for “and others”

Examples: Agency as Author

Perhaps you have a source that lists an agency, such as a government agency, as the author (and not an individual). In this instance you simply list that agency within the citation: Community policing involves developing a

relationship between citizens and the police department (U.S. Department of Justice, 2005).

Agency listed

Examples: Personal Communications Personal communications, such as e-mails,

interviews, phone interviews, etc. are cited within your text, but they are NOT listed in the reference list: Arthur Jones stated that community policing involves

developing a relationship between citizens and the police department (personal communication, May 8th, 2005).

This will NOT be listed in thereference list

References

Recall that almost without exception, your in-text citation should “connect” to an entry in your reference list toward the end of your paper. Community policing involves developing

a relationship between citizens and the police department (Jones, 2005, p. 48).Jones, A. (2005). Community Policing. Hartford, CT: Scholarly Publishers, Inc.
