    9.15.01 – CHAIN OF CUSTODY

    (revised 5/18)

    Chain of custody is the means by which we protect the integrity of evidence by providing

    proof of every person who has handled it, and that these persons have the authority to

    handle it, thereby providing proof that it has not been tampered with or altered.

    A chain of custody is the combination of documented links between the moment a piece of

    evidence is seized and when it is offered into evidence at trial. These links are the officers

    and others who handled the evidence and the times, places, and purposes of the handling.

    An officer must be able to go into a court of law, recognize the evidence (by the label or

    tag), and be able to prove that the evidence is in the same or substantially the same

    condition as when it was seized.

    When a physical transfer of location occurs of any item of property, a record will be made

    reflecting the transfer. The chain of custody shall be maintained by the following means:

    ·

    Limit the number of individuals required to handle the evidence or evidence packages

    from the time it is found to the time it is presented in court.

    ·

    If the evidence must leave the possession of the Evidence Vault:

    ➢ The person to whom the evidence is given must have legitimate business handling it.

    ➢ The person to whom the evidence is given must sign the chain of custody on the

    package face. The correct entries will be made in the property computer by the

    Evidence Vault personnel.

    ➢ The person taking the item(s) will electronically sign the property tracking history.

    ➢ All package seals must be intact before the person is given the evidence package.

    ·

    If the evidence must leave the possession of the booking officer before it is placed in the

    vault, be sure to:

    ➢ Have all persons who handle the evidence sign the chain of custody.

    ·

    If any personnel removes evidence from the vault other than for presentations to court, it

    will be documented on a Fingerprint Comparison/Evidence Processing Report Form

    (form 20.189) as to why the evidence was opened or removed. No property will be

    released without a completed copy of a Fingerprint Comparison/Evidence Processing

    Report Form.

    ·

    If a CSI is requesting to remove evidence for processing at the request of a detective or

    other officer, it will be documented on a Fingerprint Comparison/Evidence Processing

    Report Form (form 20.189) and the Evidence Vault will be given a photocopy of the form

    at the time any property is released for investigation. A report will be generated stating

    why the evidence was checked out.

    9.15.05 – RELEASING EVIDENCE FOR COURT

    (revised 4/10)

    When an officer comes to the Evidence Vault to obtain evidence, it may be released if it is

    for further investigation or other legitimate reason. The officer should have a subpoena for

    the case if it is going to court.

    The Evidence Custodian will pull packages from the vault and immediately enter the transfer

    into the evidence computer including where the evidence has gone and to whom it was

    released. Officers are to sign the chain of custody on each package and electronically into

    the property computer record immediately upon receipt.

    When officers are checking out evidence from the Evidence Vault, the Evidence Custodian

    releasing and the officer receiving will check the evidence:

    · To ensure that the proper chain of custody has been maintained.

    · To ensure that the package shows no indication of tampering or unauthorized intrusion.

    · To ensure that the package appears to contain exactly what is indicated on the package.

    If the officer subsequently has occasion and purpose to enter the package, he will confirm

    that the package contains exactly what is indicated on the package.

    If evidence is retained by the court, the officer who checked it out shall bring back the

    Evidence Transfer Receipt (form 20.143), signed and filled out by the court official taking

    possession. The completed card is brought back to the Evidence Vault and given to the

    Evidence Custodian. The Court maintains the evidence it keeps until the judicial process is

    complete at which time it is returned to our Department.

    When the package(s) return from court, the officer will return evidence directly to Vault

    personnel. If after hours, the items shall be secured in an evidence locker. The Evidence

    Custodian will sign the package(s) and return all items to their proper place in the vault.

    The appropriate entries will be made in the property computer immediately upon return of

    the evidence.

    All evidence or the Evidence Transfer Receipt for the evidence shall be returned to the

    Evidence Vault by the end of the day they were taken.

    9.15.10 – EVIDENCE DISPOSITION

    (revised 5/18)

    When a case is submitted to the Assistant United States Attorney for federal prosecution, the

    officer or detective submitting the case shall:

    ·

    Immediately notify an Evidence Custodian of the case number and status via e-mail.

    · The submitting officer shall make certain that he/she has received an acknowledgment

    from the Evidence Vault that the Evidence Custodian has received the notice of

    submission and has flagged the case in the Evidence Vault files. If a response is not

    received within five working days, a reminder shall be sent to the Evidence Vault

    Supervisor.

    Criminal cases are submitted to Municipal Court, Justice Court, District Court, and Federal

    Court. Some cases go to more than one court. When a denial is received or a case is deemed

    closed for the purpose of any future or immediate action, the investigator will notify an

    Evidence Custodian, via e-mail or a Property Disposition form, that the case has been closed

    and will not be pursued, and that either:

    · The evidence must be held until the statute of limitations for that case has run out; OR

    · The evidence can be disposed of, giving specific instructions for each item as to what

    action to take and to whom items may be released.

    9.20.01 LABORATORY SUBMISSIONS

    Narcotics Analysis

    (revised 7/13)

    With exception of blood testing in DUI or traffic collision cases, authorization for processing

    must be initiated by a detective, narcotics officer or higher authority, or by the office of the

    District Attorney or City Attorney. The request will be on the designated lab or Metropolitan

    Police Department (Metro) processing form.

    Following receipt of a properly completed request form, evidence for which narcotics

    analysis has been requested will be transported to the LVMPD Evidence Vault on the weekly

    run by NLV Evidence Custodians.

    Personnel at the receiving facility will document the receipt of the evidence and store any

    perishable items in refrigerated sections until all items are tested and picked up by Evidence

    Vault personnel. The lab chemist who does the individual test will sign chain of custody,

    including the date and time, upon proceeding with the tests.

    While at the LVMPD Evidence Vault, the Evidence Custodians will pickup any evidence for

    which analysis has been completed. Upon return, they will book it back into the NLV

    Evidence Vault making appropriate entries into the Evidence computer with electronic

    signature and signing the chain of custody each time.

    If any affidavits accompany the returned evidence, the affidavits will be given directly to the

    Office Assistant to the Detective Bureau.

    Whenever handling and transporting evidence, the packages should be examined to make

    sure the evidence is secure and seals are intact before taking receipt and signing the chain

    of custody.

    come from the Detective Bureau, CSI Bureau, or from the District Attorney and must be

    made on Bexar County Laboratory forms. Completed forms will be submitted to the

    Evidence Vault. An Evidence Custodian will remove the evidence from the vault and, after

    making appropriate entries in the Evidence Management computer, will mail the pre-

    packaged GSR test kit, first class return receipt requested, to the Bexar County Laboratory.

    Results of the test will be mailed directly to the individual requesting the test. The Bexar

    storage in the Evidence Vault.

    9.25.01 – FINGERPRINT COMPARISON REQUESTS

    (revised 5/18)

    The CSI Bureau will conduct process requests including fingerprint comparisons only upon

    receipt of a completed Fingerprint Comparison/Process Request Form (form 20.189). The

    first two sections of the form (e.g., case number, date, requested by, phone number) must be

    completed by the requesting officer.

    Upon completion of the examination, the CSI will complete the bottom section of the

    request form. In cases of urgency, the CSI will contact the requesting officer by phone.

    The CSI will then send a copy of the process request back to the requesting officer noting

    any findings, positive or negative. The CSI will complete a follow-up report to all relevant

    cases indicating findings, whether positive or negative.

    Notify CSI that fingerprints are needed to obtain a positive identification. CSI will roll a set of

    fingerprints and enter them into ABIS (Automated Biometric Identification System) first. If

    CSI does not obtain a positive identity, then CSI will fax the fingerprints to the FBI with as

    much information as possible.

    Once a name, date of birth, state ID# (SID) or FBI# has been determined by CSI or Records, a

    query will be run by CSI or Records through JLINK. CSI staff will notify the requesting person

    about positive identification and complete an information report.

    After the processing has been completed, the CSI will fill out the bottom portion of the form

    with date completed, CSI name and P#.

    All field requests for crime scene/evidence processing in which a CSI is/was unavailable,

    must be submitted to, and approved by, the field supervisor. On minor crime scenes, with no

    evidence requiring skilled CSIs, the officer may collect the evidence after documenting the

    location and photographing the evidence in relation to the overall scene. The evidence will

    be booked into the evidence facility. On more complicated scenes, field supervisors shall

    consider the following factors when making the decision to leave a crime scene unattended

    for later processing:

    · The gravity;

    · The victim’s request for processing;

    · The possibility of viable evidence contained within the crime scene;

    · The preservation and security of evidence; and

    · Personnel availability.

    If the scene is incapable of being secured until the arrival of a CSI, the field supervisor may

    assign an officer to stand by until a CSI is available to respond to the scene.

    Detectives

    (revised 3/09)

    Detectives investigating cases where processing work needs to be completed will fill out the

    request form for the appropriate processing requests. No evidence from a major crime

    scene will be processed without a process request form from the lead detective handling the

    case.

    Requests for fiber comparisons, ballistics, controlled substance, drug screen, blood alcohol,

    semen, and DNA will be sent to outside agencies and will need the applicable requests

    attached. Example: Lab form.

    Investigating detectives will not submit this form when outside agency processing requests

    are needed. Example: LVMPD processing work will be requested on their appropriate forms.

    9.30.01 – VEHICLE OR PROPERTY FIELD RELEASES

    (revised 5/18)

    When releasing a vehicle or property or seizing property in the field, the reporting officer(s)

    are to use a Vehicle or Property Field Release Form (form 20.146).

    This form is to be utilized for impounding and/or release of vehicles or property and should

    not be used to report stolen vehicles or property.

    The form consists of two copies, each having assigned requirements within the reporting

    and record-keeping function.

    · The original or white copy, once completed, shall be routed to the Records Bureau.

    · The second or yellow copy shall be utilized as a receipt for the towing company agent, or

    the owner or person in control of seized property.

    The bottom portion of the form is used to write a short narrative regarding the use of the

    form and/or describe property seized.

    Example 1:

    The driver of the above vehicle; Doe/John was arrested for DUI (Alcohol). Since no other

    licensed driver was available to take custody of the vehicle, the vehicle was impounded.

    Example 2:

    From: Doe/John DOB: 01/01/75 SS# 012-34-5678

    1234 Wherever St. N. Las Vegas, NV 89030

    One Remington, bolt action rifle, Model 700, Cal 30-06, Ser. # N123456

    The short narrative advises the clerks processing the form what may have occurred and

    protects the officer completing the form from liability.

    When using the form to receipt for seized property, the officer will check the "OTHER" block

    at the top of the form and write "Receipt" in the upper right corner.

    Once the form is complete, leave the yellow copy with the owner or person in control of the

    seized property.
