Joshua Matthew Grose

— The double homicide suspect who died in the York County Detention Center in October suffered a brain hemorrhage after hitting his head against a jail cell wall numerous times, the York County Coroner’s Office said on Tuesday. His death has been officially ruled a suicide.

On Oct. 18, deputies charged Joshua Matthew Grose, 34, with two counts of murder and one count of attempted murder after they say he stole neighbor Sandra Thomas’ car and ran over her and his stepmother, Sandra Grose, 65, killing them both. Authorities say he also nearly beat to death his uncle, Curt Allan Sisk, 60.

Grose died two days later, after a nearly two-hour struggle with detention center guards in which he became violent and combative. He fought against officers, even grabbing onto one’s legs, after they tried to stop him from banging his head repeatedly against a wall.

Officials placed Grose, wearing a football helmet, in a restraint chair, but he continued to struggle. Jailers put him in a cell, but the chair was positioned in a way that allowed him to throw his head backward against the chair and a cell window. He was found unresponsive at about 2:30 a.m.

After performing CPR for nearly 20 minutes, an EMS crew took him to Piedmont Medical Center, where he was pronounced dead.

Preliminary autopsy results showed that he died of blunt force trauma to the head, York County Coroner Sabrina Gast said. That theory held after an extensive autopsy showed he suffered from bleeding on the surface of his brain and in the thin layer of tissue that separates the brain from the skull.

Gast has officially ruled his death a suicide, and toxicology results, which show what substances were in the body at the time of death, are not considered contributing factors to Grose’s death. Those toxicology results were not immediately available.
