From homeless to class speaker, one of Detroit's newest officers has a remarkable story to tell

Randall Davis was this session's class speaker for the Detroit Police Academy's graduating class, telling a remarkable triumph over tragedy story.

When Davis was 16, his father shot his mother before committing suicide.

"Then I hear a gunshot and I immediately wake up. And it was right in front of me and I yelled 'Dad' and he just never looked at me, he just put the gun to his head and he shot himself," said Davis.

That was Sept. 6, 2006, more than a decade ago. It feels more like a mirage for Davis.

"You never know it's real, I just - at this point I'm still dreaming," he said.

Orphaned as a teenager with young siblings, it was left to Davis to watch over what was left of his family.

"And then the kids are left to fend for themselves, especially if they don't have any loved ones that really care for them, to help them through the situation," he said.

"Most of it was myself and I had to strap my boots on and I had to keep moving," he added.

They eventually moved in with family, but that didn't last long for Davis. He and his older brother moved out and ended up on the street, sleeping in cars and empty homes.

"I was homeless, sleeping in cars, trying to make sure I ate," Davis said. "Me and my brother Brandon, we were in vacant houses just trying to survive."

Around the time Davis' daughter was born, he made a decision to reverse course. He says he was tired of "feeling used" and "arguing with people." So he made a change. 

He worked hard, lost 70 pounds and enlisted in the academy. In November, that hard work paid off when he was granted the honor of telling his story to his fellow graduates. And with such a story comes a few lessons along the way.

"I want teenagers, and even kids, who feel like they don't have anybody that you have to keep pushing. That's the biggest lesson that I have learned and that's why I want to help them," said Davis.
