The family of Roger Dale Crisp is offering a $20,000 reward for information leading to the arrest and conviction of the person or persons responsible for Roger's death.

Over four months ago, police found the body of metro man in a burned mini-van. So far, there have been no arrests in the case.

November 9, 2007, Oklahoma City police found the body of Roger Crisp on the floor of his mini-van near Mustang Road and SW 44. Roger and his car was severely burned.

Oklahoma City Police Sergeant Gary Knight said it wasn't the fire that killed him.

"He had multiple stab wounds; the medical examiner determined that was what the cause of death was," Knight said.

There have been no arrests in this case, and as the months passed, it has become increasingly frustrating for Roger's family.

"We want answers, we want to know why," Roger's wife Jerri said. "What did he do so wrong to make you have to do this to him."

This past weekend, Roger's family held a fundraiser in Texas, near Roger's hometown. They raised $20,000 that they are now offering for information about the death.

"I know somebody has got to know something; nobody could do that and somebody not know, somebody not see," Jerri said.

Police say Roger may have been around SE 66 and Shields or near Interstate 240 and Eastern the night he was killed.

Jerri describes her husband as a fun loving man who didn't start fights. She can't understand why anyone would want to hurt the man she built a life with for almost 23 years.

Police also believe someone has information about this case saying it is very unusual for only the killer to know about a homicide.

OCPD Homicide detectives said they have exhausted all leads in this case and are seeking the public's help in uncovering new information.

If anyone has any information related to this murder, police ask they call the OCPD Homicide Unit at 297-1126 or Crime Stoppers at 235-7300.
