The Murder of Brianna Denison
The Manhunt is On
By early April 2008, police had received more than 4,000 tips in the case, but none of them had led to a suspect. The Regional Sex Offender Unit, which comprises officers from the Reno and Sparks police departments and the Washoe County Sheriff's Office, interviewed 100 sex offenders residing within a mile of the MacKay Court residence, and contacted more than 1,700 registered sex offenders living in Washoe County, creating a backlog in DNA processing. Funds were quickly raised to help speed up the process, but a suspect remained elusive.
