ROUND ROCK (CBSDFW.COM/AP) — A Texas county sheriff says an officer has been shot and killed at his home in Round Rock, just north of Austin.

Travis County Sheriff Greg Hamilton said at a news conference that the body of Sgt. Craig Hutchinson was found early Monday in the backyard of his home. Hutchinson was a 32-year veteran officer who was set to retire in September.

The Sheriff said Hutchinson used his police radio around 1:30 a.m. to report people were in his backyard. Investigators arrived moments later and discovered his body.

No arrests have been made but Hamilton said authorities are looking for several suspects. He said there had been reports of robberies in the area and that there was evidence the incident was an attempted robbery of Hutchinson’s backyard shed, rather than an ambush targeting him as a law enforcement officer.

Police temporarily shut down lanes of Interstate 35 as Sgt. Hutchinson’s body was taken from the hospital to the Travis County Medical Examiner’s Office.

Tensions remain high following the fatal shooting earlier this month of five police officers in Dallas and the ambush and killing of three law enforcement officers in Louisiana.
