SPRINGFIELD, Mo. -- It's been six months since the body of a man from Springfield was found floating in the James River at the Crighton Access.   The Greene County Sheriff's Department urges anyone who knows anything about the homicide of James Richardson, 27, to come forward.

Sheriff Jim Arnott said he has two detectives working this case.  So far, 65 people have been interviewed and about 120 pieces of evidence have been collected.  The evidence has been sent to the crime lab and some of it has been retested as recently as last week.

Authorities know how Richardson died, but won't release the cause because they said doing so could hinder the investigation.

The sheriff said this case has been challenging, because people who might know something aren't talking.

"The unfortunate thing in this case is we know that there are friends and associates that have direct information on it, and we need them to cooperate," said Arnott.

The sheriff hopes someone's conscience will prompt him or her to come forward and do the right thing.  If that doesn't happen, "We're hoping cash will," he said.

Crime Stoppers is offering a $5,000 reward for the arrest and conviction of the culprit or culprits, and the sheriff's office is pitching in an additional $2,000.

Anyone with information should call (417) 869-TIPS.
