YORK, S.C. (AP) — A Rock Hill man accused of killing his mother and a neighbor, and injuring a third person, died early Sunday after officers found him unresponsive in his York County jail cell.
Joshua Grose, 34, was pronounced dead about 3 a.m. Sunday at Piedmont Medical Center, after he repeatedly hurt himself in jail. An autopsy will be performed Monday to determine cause of death, said sheriff’s spokesman Trent Faris.
Officers stopped Grose earlier Sunday from drowning himself in his jail cell toilet. They put him in a restraining chair for his own safety after he hit his head against the cell wall. But “he was still very, very combative” and continued to hit his head against the back of the chair, Faris said.
When officers attempted to put a helmet on him, they noticed a cut on the back of his head. Paramedics were called but said the cut didn’t require stitches, so authorities chose not to transfer Grose to the hospital then. Because he was so combative, a full medical exam couldn’t be performed, Faris said.
Grose was in cardiac arrest when paramedics were called back about a half-hour later, he said.
Grose faced charges of murder, attempted murder and grand larceny. Faris said Grose had been uncooperative and combative with officers since he was booked into the jail about 11 p.m. Friday.
Authorities accuse him of running over 53-year-old Sandra Thomas while trying to steal her car. Faris said he then went to the home of his mother, 65-year-old Sandra Grose, where he assaulted her and hit her with the car. In the process, he also assaulted 60-year-old Curtis Sisk. Both women were found dead in their yards Friday. Sisk was taken to the hospital. Sisk’s relationship to the Groses isn’t yet known, Faris said.
Both women died of blunt force trauma to the chest, according to Coroner Sabrina Gast.
Faris said a motive remains unknown.
The State Law Enforcement Division is investigating Joshua Grose’s death.
“All of our detention officers did exactly what they were supposed to do last night,” Faris said.
