CHRISMAN - The Illinois State Police are marking today's three-year anniversary of the unsolved double homicide in rural Chrisman by making a renewed call for tips in the case.

The bodies of Mark Prasse of Chrisman and Ryan Riddell of Villa Grove were found by police on Jan. 28, 2008, in Prasse's home in rural Chrisman. They had been shot to death. Investigators announced on the two-year anniversary that they suspect the two friends, both 32 at the time of their deaths, may have been victims of a targeted killing.

An ISP press release reported that the investigation remains a priority and is still assigned to the Zone 5 Investigations General Criminal Squad in Champaign.

Zone 5 continues to work closely with the Edgar County Sheriff's Office, Paris Police Department, Edgar County Coroner's Office, Federal Bureau of Investigation, and the Edgar County State's Attorney's Office in an effort to solve this case.

With assistance from the above agencies, ISP investigators continue to follow up on all existing and new leads. To date, nearly 1,000 leads have been opened and investigated. Of these, many have led to additional follow-up assignments within and outside of Illinois.

In addition, numerous items of evidence have been seized, many of which have been and are currently under forensic and scientific testing.

ISP reported that no additional information will be released at this time and that any significant new information will be released to the news media as it develops. Investigators have said they believe the killer or killers knew Prasse and Riddell, and have found no evidence that either of the two men were involved in any criminal activity.

Prasse and Riddell met while attending the University of Illinois and became best friends. Prasse worked at North American Lighting in Paris and Riddell worked on his family farm. Riddell was married and had a son on the way at the time of his death.

Lastly, ISP has reminded the public a reward of $25,000 remains in effect for information leading to the arrest and conviction of the person or persons responsible for this crime. Anyone with information concerning these homicides is encouraged to call ISP's 24-hour tip line at 278-5004.
