MANCHESTER, Tenn. (CBS/AP) Matthew Perkins, a soldier who served in Afghanistan and Iraq, is accused of killing his girlfriend and her two young children, stuffing their corpses into plastic garbage bags and hiding them in a closet for days.

A neighbor says he noticed an unusual stillness at the house normally busy with the toddlers and their friendly mother. When police in this small town investigated a missing person's report Wednesday night, they said they found a "very gruesome" crime scene that rattled even veteran investigators.

"It's the worst I've seen, and I've been here 30 years," said Ray Stewart, a police investigator in this town of 10,000 that hosts the Bonnaroo Music and Arts Festival each summer.

Manchester Police Chief Ross Simmons identified the victims as 26-year-old Stephanie Hershman and her sons, 3-year-old Jathan and 1-year-old Jaylon.

Police said Perkins, of Tullahoma, told someone Wednesday night that he had killed the family, and the person went to police. The

The 30-year-old U.S. Army recruiter is charged with three counts of first-degree murder and is being held in the Franklin County jail on a $6 million bond.

Army records show Perkins enlisted in 2000 as an infantryman out of Murray, Ky., and served in Afghanistan from April 2004 until April 2005 before a tour of Iraq, from August 2006 until October 2007. He has been a recruiter in Tullahoma since July 2008.

His arraignment was set for Tuesday.

Police believe the three were killed on Sunday. They did not release a cause of death but said the bodies have been turned over to a medical examiner.

Perkins was not the children's father. Investigator Billy Butler said Perkins is separated from his wife of 10 years, Jennifer Perkins. She was at the police station for questioning on Thursday morning, but declined to speak to the media.
