LEXINGTON, N.C. — The Davidson County District Attorney said he asked a judge Friday to unseal a search warrant in the fatal shooting of a man who had taken three people hostage.

District Attorney Garry Frank said he sent the request to Superior Court Judge Mark E. Klass, who had not signed the order as of Friday afternoon, according to office staff.

Aubrey Roy Roseberry, 58, was shot and killed by sheriff's deputies Wednesday night after taking three people hostage at a home near Lexington, authorities said.

Sheriff David Grice has said one man escaped from the house before Roseberry took a 13-year-old boy, a 17-year-old girl and a 30-year-old woman hostage. The man who escaped and the three hostages each were shot during the ordeal.

Roseberry released the girl and woman after about three hours of negotiating, and he was shot as he tried to escape. Deputies then found the boy alive inside the home, with a bullet wound to the head.

Frank declined to release the victims' names or medical conditions. State Attorney General's Office spokeswoman Noelle Talley also declined comment on the victims.

Talley said the State Bureau of Investigation is handling the case at the request of Frank and Grice.

"Once the agents finish their investigative work, they will give their findings to the district attorney," Talley said. The state Attorney General's Office oversees the SBI.
