A career criminal will be locked up for at least 10 years for robbing a Newberry Township convenience store at gunpoint as he was on his way to York from the state prison in Camp Hill, where he'd just visited his incarcerated son.

David Lee Carmichael, 52, with addresses in Oxon Hill, Md., and Alexandria, Va., pleaded guilty Tuesday to robbery and was sentenced to 10 to 20 years in state prison for the May 14, 2011, holdup at Hess Express, 55 Robin Hood Drive.

He told the woman working there he'd shoot her head off if she didn't hand over all the money in the store, Newberry Township Police said.

He made off with $800 cash and $1,300 worth of cigarettes during the 1:30 p.m. robbery, police said. Before leaving, he told the clerk, "You got lucky today -- you aren't going to die," according to court documents.

Also on Tuesday, Carmichael pleaded guilty to robbing the Tom's convenience store at 2905 E. Prospect St. in Windsor Township on May 13, 2011.

Death threats: The 6-foot-1, 250-pound Carmichael pointed a handgun at the clerk and demanded cash, telling her several times he was going to kill her, according to York Area Regional Police.

He was sentenced to 10 to 20 years for that robbery. Common Pleas Judge Michael E. Bortner ordered the two sentences to run concurrently, court records state.

Chief public defender Bruce Blocher, who represented Carmichael, declined comment.

At the time of the holdups, Newberry Township Detective Keith Farren told The York Dispatch that Carmichael apparently had been staying "with a couple girlfriends, or mothers of his children in York City."

Long record: The detective also confirmed Carmichael was driving home from visiting his son at the state prison in Camp Hill.

"He has a very, very lengthy criminal history and has served time for armed robberies and kidnapping," Farren has said of Carmichael, which goes back to the 1970s and includes felonies in Pennsylvania, Virginia, Maryland and Washington, D.C.
