A 25-year-old inmate of the Alvin S. Glenn Detention Center committed suicide Friday, Richland County Coroner Gary Watts said Saturday.
Joshua L. Sullivan was in a cell by himself at the time of his death, Watts said.
A guard making routine rounds on Friday found Sullivan hanging in his cell, Watts said. Efforts to resuscitate him were unsuccessful. An autopsy indicated Sullivan died from “asphyxiation due to hanging.”
Sullivan had not been on suicide watch, Watts said. There was no evidence of foul play, Richland County Sheriff’s Department spokeswoman Arielle Riposta said. The sheriff’s department continues to investigate.

Sullivan was booked June 27 on charges of third-degree arson, possession of tools that could be used in a crime and malicious injury to animals or personal property, according to Melinda Edwards, who works for Richland County, which manages the jail.
Sullivan was accused of throwing a Molotov cocktail through a window at the Department of Probation, Parole and Pardon Services office, at 1221 Gregg St.
Office employees reporting to work around 6:30 a.m. on June 27 called the fire department when they saw a broken window and smoke inside the building. Crews quickly put out the fire, and damage was minimal. Sullivan, who told Columbia police he lived at a Gregg Street address, later admitted to the firebombing, Columbia Fire Chief Aubrey Jenkins said at the time.
