MIAMI COUNTY, Ind. — An inmate at the Miami Correctional Facility was stabbed to death Monday, according to Indiana State Police.

ISP identified the inmate as 23-year-old Jamar Greer.

State police investigated the incident and found that at about 4 p.m. Monday, correction officers found Greer suffering from a stab wound in the day room of the “L” housing unit. Prison staff provided medical treatment until Greer was taken to a hospital, where he died.

A forensic pathologist determined that Greer’s death was a homicide caused by a stab wound to the chest.

ISP said preliminary evidence revealed that another inmate stabbed Greer with a “homemade knife.” That inmate is known to investigators and has been separated from other inmates, state police explained.

An investigation into the homicide is ongoing.
