ROCK HILL — A 34-year-old Rock Hill man is responsible for killing both of the women found dead Friday night in the River Pines subdivision off Mount Gallant Road, authorities say.
A third victim, a man, was injured in one of the incidents, authorities said.
Late Saturday afternoon, the York County Sheriff's Office said both women were killed when they were hit by a vehicle.
Joshua Matthew Grose, 34, was charged Friday night with killing Sandra Thomas, 53, of 5296 Woodside Drive in Rock Hill. On Saturday, deputies said he also killed the second victim, whose identity has not been released because relatives have not been notified. As of late Saturday morning, Grose had not been formally charged in that killing.
The women were killed at separate locations between 6 p.m. and 6:15 p.m. Friday. The crime scenes are on Woodside Drive and in the area between Mount Gallant Road and Kingswood Drive northwest of Rock Hill between the city and Lake Wylie.
Thomas lived at the corner of Woodside and Kingswood Drive. Woodside Drive runs parallel to Mount Gallant, but is only about 100 yards north of Mount Gallant. Thomas was found dead at the house. She died of chest injuries, said York County Coroner Sabrina Gast.
A neighbor on Woodside Drive, Lou Cannon, said that police have not given neighbors any details about the killings. He said Grose, of 5316 Mount Gallant Road, lived directly behind Cannon's house.
"She was a very nice lady, Sandra," Cannon said. "This is a quiet neighborhood. Most of the time."
However, Cannon said that Grose, had acted erratically previously and police had been called by a different neighbor to investigate.
Authorities have not released any details about how the women were killed. A motive for the crimes remains unclear, said Trent Faris, a sheriff's office spokesman.
Grose, who is in jail, was sent to prison in 2012 after convictions for DUI and other traffic offenses, according to online court records. Grose was convicted of a drug offense in 2004, court records show.
He has not yet appeared before a magistrate on the murder charge. The sheriff's office jail Web site shows that Grose is charged with one count of murder, but is also being held for other warrants. It is unclear what those warrants will be.
Sheriff Bruce Bryant told The Herald that Grose had been seen at both crime scenes.
Bryant assured the public that they are safe and no suspects are on the lose.
We are trying to unscramble the mystery of what took place, Bryant said Friday night.
