Tooele County officials confirmed Tuesday evening that the lock down was prompted by the self-inflicted shooting of a Tooele County Sheriff's Deputy.
The sheriff's office along with Utah Highway Patrol, Grantsville Police, Tooele Police and Adult Probation and Parole responded to the home at around noon after a report of hearing shots fired from the residence. The deputy was found dead inside.
All three schools in Stansbury Park were put on lock down until around 1:30 p.m. The incident is being investigated by the Tooele City Police Department.
