DEFIANCE, Ohio (AP) – Authorities in Defiance County are waiting on autopsies for four people who died in what is being investigated as a triple murder-suicide.

Defiance County authorities say autopsies of 68-year-old Robert Garza Sr.; his wife, 61-year-old Christine Garza; his 42-year-old daughter, Zoila Garza; and his 15-year-old granddaughter, Rebecca Garza, were being conducted in Lucas County.

Their bodies were discovered Thursday in their home in Defiance. Investigators believe the grandfather killed the others and then himself.
