TWIN FALLS, Idaho (AP) — Idaho authorities say initial findings indicate a Twin Falls County man used a shotgun to kill his longtime girlfriend and one of her five children before using the same weapon to kill himself.

Twin Falls County Prosecutor Grant Loebs says autopsy reports have not been finalized from the Nov. 15 deaths but the early investigation has found only the single weapon. Police say 36-year-old George Salinas likely killed 38-year-old LeAnn Schuldies and her 17-year-old daughter, Brianna Cox, before ending his life.

Their bodies were found in a Twin Falls County home. Four other children ages 6, 7, 9 and 13 survived. Schuldies was a well-liked Twin Falls bartender. She had an order of protection against Salinas and was trying to end her relationship with him when she and her daughter were killed.
