A preliminary investigation reveals a family of four was shot to death Thursday night at a Defiance home.
Defiance County Sheriff's Office said a family member went to 25237 Bowman around 7:30 p.m. to check on the family's welfare.
Officials discovered the bodies of Robert Garza, Sr., his wife, Christine Garza, daughter, Zoila Garza and granddaughter Rebecca Garza.
Officials believe that Mr. Garza killed all three female victims before turning the gun on himself.
Deputies remained at the scene late Thursday night, as they interviewed neighbors, family and friends.
Authorities planned to be at the crime scene until Friday morning, according to a news release from the Defiance County Sheriff's Office.
