Authorities are awaiting the results of forensic evidence testing in their investigation into a murder/suicide in North Canton.

NORTH CANTON  Officials are awaiting the results of toxicology tests and other forensic testing as they continue to investigate the murder-suicide that claimed a father and son early Monday morning.

Police and Ohio Bureau of Criminal Investigation officers are continuing to investigate, Sgt. Frank Kemp of the North Canton Police Department said Tuesday.

Ronald Milliken, 49, of Harmont Avenue SW was found with multiple gunshot wounds to the chest as he sat in a recliner in his living room, said Rick Walters, investigator with the Stark County Coroner's Office.

Milliken's son, Devin Milliken, 18, was found a short time later, dead of an apparent self-inflicted gunshot wound near the Witwer Park restrooms, which are a short distance from the home and within view of North Canton Middle School, police said. School officials closed the school Monday as authorities conducted their investigation.

Autopsies on both Millikens were conducted later Monday, but no ruling has been made pending the results of forensic testing from the state crime bureau and the Stark County Crime Lab.

It has been eight years since anyone became a homicide victim in North Canton, Kemp confirmed. Police said the last homicide took place in 2008 when Brett Smith was murdered in his trailer. His neighbor, William D. Perry, admitted to beheading Smith.

Perry is serving a life sentence for aggravated murder, aggravated burglary, aggravated robbery, evidence tampering and abuse of a corpse.
