Aaron Walker says Joseph Walsh, or Joey as he called him, was a good stepdad and a wonderful grandfather to his children.
"When my first one was born, it was in Weatherford, and it was one o'clock in the morning, and I said, 'Hey, he's coming.' And he got in the truck and came down," says Walker.
He says Walsh would do anything for his family. His youngest son, Joe-Joe, is even named after him. That's why he was in disbelief when he got the phone call from his wife yesterday.
"She said that there was a stand-off and Joey killed an officer, wounded another and then was killed. And I hit the floor. My first reaction was, I was mad at him, because he did make a promise to me that nothing would ever come between him and my sons," said Walker.
Aaron's mother, Cathy, told us today, this is how everything started. She was asleep inside their house, when she heard a gunshot. When she went to investigate, she found her husband, Joseph Walsh, locked in a room with a cedar chest pushed in front of the door.
"She got the door open, and she said she looked at him and it wasn't Joey. He grabbed her and was choking her on the couch and tore out the front door, and that's when she ran and to call the cops," said Walker.
Today, Cathy is dealing with guilt, saying maybe if she hadn't called for help, Constable Geddie and her husband would still be alive.
Aaron says he'll never know what caused Walsh to snap yesterday. He says maybe the stress of life finally caught up with him.
"He was sick. He was on medication. He was diabetic. He just had everyday problems like everybody else had. Normal stresses, family stresses."
When asked if he thought those stresses were too much, he said, "I do."
When asked what he wanted to say to the officers' families he just wept, saying he wished things had turned out different for all of them.
"I'm sorry that the other families had to go through it, too. None of us should. There were a lot of families destroyed."
