Allen County Sheriff Sam Crish says 45-year-old Randy Glenn walked into the house of his estranged wife Carlin Glenn at 9 Beaumont Place just after 4 this morning.
"I woke up at about 4:15 hearing gunshots, I heard 4 gunshots," said neighbor Diane Clark.
The first gunshot was when Glenn fatally shot his 20-year-old daughter Andrea Glenn. Sheriff Crish says the mother than ran over to the house across the street, and that's when he shot her in the driveway.
He then returned to his home and killed himself with the same handgun.
Authorities say Glen's wife filed a report Wednesday night saying he was sending her harassing text messages. However, Executive Director of Crossroads Emily Wrencher says she probably never thought the harassment would escalate to this level.
"If they were estranged, there was no predicting. You can't predict what's going to set a batterer into motion," said Wrencher.
Although cases like this one are rare, Wrencher says they almost always follow a pattern. She says shooters kill their loved ones and themselves because they want to have total control of their spouse or child. It's the "If I can't have you no one can mentality".
Sheriff Crish says the shooter's 17-year-old son was also in the home at the time of the shooting,but he was not hurt.
