BROKEN ARROW, Oklahoma - The family of a missing Broken Arrow man is demanding answers.

Justin Cobb, 34, disappeared five months ago and police still don't know what happened to him.

Cobb was last seen on Aug. 10.

His family said it's not like him to just up and disappear, and they believe someone knows what happened, they just aren't talking.

Cobb is a family man, married with three step children.

"I don't know anybody, anybody who hates Justin or didn't like Justin," uncle Ernest Cobb said. "Everybody loved Justin."

On Aug. 10, his family says he didn't show up for work at Mullin Plumbing.

Then nearly one week later, Justin's work van was found in a field near Haskell.

His wallet -- full of credit cards and cash -- his laptop and clothes were all found inside the van, but no sign of the 35-year-old husband and father.

"If they found his truck up in the woods in Haskell on 310, somebody had to have a vehicle hid up there where they could get out," Ernest Cobb said.

Ernest Cobb said he and his wife, Margaret, immediately started posting fliers, hoping someone would come forward with information.

They're tired of waiting.

"Too long," Margaret Cobb said. "It's been five months. We don't know where he is. We don't know. We just don't know."

The Cobb's aren't sure what happened to their nephew.. but they fear the worst.

"Long time for someone to disappear, very long, long time," Ernest Cobb said. "I think he's dead to tell you the truth.

"Somebody's hiding stuff about my nephew. I want to know the truth."

There are plenty of rumors flying around about what happened.

Some speculate Justin Cobb was using drugs, but his uncle said there's no truth to that.

"It really hurts you, because I seen him grow up from little bitty to a man," Ernest Cobb said.

Margaret Cobb: "Justin's a kind, tenderhearted man who will give anything to you or whatever."

The family said all it wants is to find Justin to properly say goodbye.

"I don't want to wait another 5 or 10 years to find out," Ernest Cobb said. "I want to find out now, so does his dad and his mama."

The Broken Arrow Police still are investigating Justin Cobb's disappearance.
