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

Chapter 9.15

NORTH LAS VEGAS POLICE DEPARTMENT – POLICE PROCEDURE MANUAL

Page 1 of 4

PS/PR 9.15

CHAPTER: EVIDENCE AND PROPERTY

SUBJECT: CHAIN OF CUSTODY, RELEASING EVIDENCE FOR COURT, EVIDENCE DISPOSITION

(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

Chapter 9.15

CHAPTER: EVIDENCE AND PROPERTY

SUBJECT: CHAIN OF CUSTODY, RELEASING EVIDENCE FOR COURT, EVIDENCE DISPOSITION

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.

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

CHAPTER: EVIDENCE AND PROPERTY

SUBJECT: FINGERPRINT COMPARISON/PROCESS REQUESTS

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.
