JACKSONVILLE, Fla. -

This week marks one year since Robert "Bob" Levey was murdered in his own home, and there still has been no arrest in the case.

Levey's body was found June 25 in his home on Mimosa Drive. Levey worked as an audio engineer for a local television station for several years.

Saturday, MAD DADS and Levey's loved ones were pushing for new information and answers.

"We thought that within a matter of days or weeks, that our family would have closure," said Robert Levey's son, Russ Levey.

Russ Levey never imagined that after one year, there would still be no answers in his father's case.

"Lt. Schoonover called it a brutal homicide. What does that mean? That's even worse," said Russ Levey. "What, did someone kill our dad in a brutal manner? And apparently they're still walking around free amongst us."

Robert Levey's family said his home was set on fire after he was killed. People gave a description of a man seen near the property at the time of the fire, but he hasn't been found.

Russ Levey describes his father as a man with a kind heart, a good sense of humor, someone who enjoyed cutting up with his coworkers at the TV station.

"He had some compassion. All around a good guy," said Russ Levey.

"I mean, this family has been grieving for a whole year now. We know someone in the community knows something," said Al Jordan with MAD DADS. "That's why MAD DADS is going back on there. We are not giving up on our families."

"We're going to continue to be out here on the streets. We're going to continue knocking on doors, handing out fliers until we catch them all. It's either all or none."

Despite everything, Russ Levey still believes his father's case can be solved, if the right person comes forward.

"Even a hard sell, like me, as far as religion, I have found some faith. I have found some hope," said Russ Levey. "I think sometimes that's all you have."
