CHAMBERSBURG, Pa. (CBS/AP) — A second person has died of injuries suffered in an explosion and fire last month at an Army facility in Pennsylvania.

The Letterkenny Army Depot’s commander, Col. Stephen Ledbetter, says the employee died Thursday at the hospital where he has been treated since the accident July 19.

The Army did not identify him, but family members say his name was Rick Barnes.

At the time of the fire, Army Depot officials quickly posted on social media the incident was contained, that operations elsewhere on the base would not be affected and that there was no suspicion of terrorist activity.

“The Letterkenny Army Depot family deeply mourns the loss of another invaluable team members as a result of the industrial accident that took place on July 19th,” said Col. Ledbetter.

A GoFundMe page set up for the victim’s family says he suffered burns over about half of his body and that he was treated at Johns Hopkins Bayview Medical Center in Baltimore.

Five employees were injured in the explosion and fire. One died the same day, two others were treated for smoke inhalation and another employee remains hospitalized.
