Natrona County Sheriff's Office

The Natrona County Sheriff's Office said search efforts include tracking experts, search dogs, mounted searchers and drones.

The search for an autistic Natrona County teen missing since Sunday afternoon has entered his fourth day.

Peterson is 5'9" and weighs 120 lbs. He was last seen wearing a red hooded sweatshirt and pajama pants.

Beginning at noon Sunday, a task force consisting of 10 city, county, state and federal agencies has been taking part in the search.

His physical description is consistent with that of the man who fell into the water on Sept. 7, authorities say.

The sheriff's office was notified regarding the incident at roughly 7 p.m. Saturday.

Tamblyn, who is incarcerated, hung his head as District Court Judge Kerri M. Johnson read the sentence.

The victim was taken to Wyoming Medical Center, where he died of his injuries.

Wyoming Medical Center shooting suspect Mitchell Taylor has yet to appear for his arraignment in Natrona County District Court.

One victim had gotten up and walked toward his dresser to extinguish his cigarette when the bullets came through the window.
