The Evidence Unit safely stores, protects, accounts for, and disposes of seized, abandoned or recovered property or evidence retrieved from a crime scene.

Evidence plays a vital role in criminal investigations. TPD's Evidence Technician will process, maintain, and document the handling of evidence using a Chain of Custody. Not only does the Chain of Custody help establish elements of the crime, but it can also help identify a victim or a perpetrator. When a case goes to trial, a judge and jury rely on evidence to decide a defendant's guilt or innocence.

Common types of evidence include:

  • Photographs
  • Videos
  • Blood
  • DNA Samples
  • Documents
  • Articles of Clothing
  • Digitally Stored Data

If you have any questions about retrieving seized evidence or found property, please call 360-716-5968.

The Sex Offender Monitoring Unit is led by the SORNA Program Manager, who is responsible for managing and registering sex offenders as well as handling all of the day to day operations of the Tulalip Tribal Police Department Registered Sex Offender Program.

Protecting the community from sex offenders is of the utmost importance to the Tulalip Tribal Police Department’s SORNA program. Information that is relevant and necessary to protect the public and to counteract the danger created by a particular offender is released to the community under the sex offender registration Tulalip Tribal Code.

This can include those sentenced for sex or kidnapping offenses, sexually violent predators, sexual psychopaths, offenders found not guilty because of insanity, and any person found incompetent to stand trial and subsequently committed.

The extent and content of the disclosure of relevant and necessary information shall be related to:

  • The risk the offender poses to the community.
  • The location where the offender resides, intends to live, is regularly found, or is employed.
  • Impacted community members need information that protects their interests and safety.

The Tulalip Tribal Police SORNA Unit uses an online sex offender registry, which shows where in your neighborhood sex offenders live, along with other information.

SORNA also meets with sex offenders in the community every 90 days for an in-person interview and with the transient / homeless every Monday morning. Every December, photos of offenders are updated.

*SORNA stands for Sex Offender Registration and Notification Act and was established by
Title I of the Adam Walsh Child Protection and Safety Act of 2006.
