Authorities say the shot that killed a Texas sheriff's deputy at his home last week came from his own service weapon.
Round Rock police Chief Allen Banks said during a news conference Wednesday that investigators have not yet determined whether Travis County Sgt. Craig Hutchinson killed himself or whether someone took his gun and used it against him.
Authorities previously said Hutchinson used his police radio around 1:30 a.m. on July 25 to report people prowling behind his house.
Investigators arriving moments later found the 32-year law enforcement veteran lying on the ground in his backyard in Round Rock, about 15 miles from Austin.
