Crime Fighters: Who killed Michael Molinario?

CLIFTON HEIGHTS, Pa. (WPVI) -- Stephen Miller and Michael Molinario worked together for years at Miller's business, Miller and Miller Asphalt.

On Friday Nov. 21, 2014, Miller paid Molinario for the week's work and the two went their separate ways.

"The following morning I called Mike, and Mike never answered his phone, and that kind of through me off," said Miller.

Authorities said Molinario went to the Rams Head Bar in Clifton Heights, Delaware County, and wasn't seen since.

Officials searched for days for Molinario. Then on Dec. 2, his body was found in the back of his truck at the Willows Apartment Complex.

He died from blunt force trauma to the chest, police said.

"He was a great, great reliable guy. He was a proud guy to be a marine, and he wouldn't let you down," said Miller. "I really want justice, you know, I think about Mike all the time."

And even though they were divorced, Molinario's ex-wife, Donna, said she's speaking out for her twin daughters who miss their father.

"My girls just asked me to try and find closure for them, and that's what I'm doing," said Donna Molinario.

The Citizens Crime Commission is administering a $5,200 reward for the arrest and conviction of the person responsible.
