Police are investigating the death a Columbia man stabbed late Friday night, Jan. 15, in his home.
Columbia police have charged Ronald Lee Sheetz, 41, with criminal homicide regarding the death of 44-year-old Michael Oberdorff Sr.
At the time of this release, Sheetz is not in custody. He is presumed dangerous, so anyone who sees him or knows of his whereabouts, call police immediately at 684-2120. Do not try to confront or apprehend him.
Investigators, including Columbia police and Lancaster County detectives, are actively pursuing Sheetz, whose last known address is in Columbia.
Police were dispatched to 322 South Second Street on Friday about 11:35 p.m. for a reported domestic incident in progress.
Police were met by a woman who lived there, reporting that her husband, who was in an upstairs master bedroom, needed help.
In the master bedroom, police found Michael Oberdorff Sr., on the floor with an apparent stab wound to his chest.
Oberdorff Sr. stated to an officer, "Help me! Help me! I'm dying. Ronald stabbed me."
Oberdorff Sr. died a short time later at Lancaster General Hospital. He was pronounced dead at the hospital.
During an interview with police, the woman occupant identified "Ronald" as Ronald Sheetz, a former boyfriend. She told police she saw Sheetz in a physical altercation with her husband.
Columbia police Officer Edgar Mann filed charges, which were approved by Lancaster County Assistant District Attorney Christopher Lechner.
An autopsy is scheduled for Monday.
Sheetz is presumed innocent.
