The Colorado Bureau of Investigations (CBI) is conducting an independent review into the death of Megan Trussell, whose body was found a year ago in Boulder Canyon. The Boulder County Coroner had ruled her death a suicide, but Trussell's parents dispute that conclusion and believe there was not a sufficient investigation. The CBI review was initiated after the parents requested it under a new state law aimed at improving investigations of missing and murdered indigenous persons.

Why it matters

This case highlights the ongoing challenges families face in getting thorough investigations into the deaths of their loved ones, especially when the initial findings are disputed. The independent CBI review could provide more clarity on the circumstances surrounding Trussell's death and address the concerns raised by her family.

The details

The Boulder County Coroner's Office ruled Trussell's death a suicide in May, citing toxicology results and undigested prescription medication found during the examination. However, Trussell's parents believe there were other potential causes that were not sufficiently explored. The CBI review will not be a full re-investigation, but rather an independent assessment of the case. Officials from the Boulder County Sheriff's Office, Coroner's Office, University of Colorado Police, and District Attorney's Office are all supportive of the review process.
