A Dauphin County Prison guard is facing murder charges in a deadly home invasion and botched robbery last year.
 
Investigators say Lebron Johnson was involved in planning the robbery and was at the scene when Cung Duong was shot to death inside his home on South 19th Street December 10. Police picked up Johnson on Tuesday during his shift at the Dauphin County Prison and led him away in handcuffs.

Johnson is the sixth man charged in the murder of Duong, a businessman who owned a pool hall next to his home. Prosecutors say the suspects believed Duong kept large sums of money at his house.
 
Investigators say Johnson was friends with the co-defendants. They believe Johnson was there to provide some muscle.

As his wife was held down in another room, police say Duong fired back at his attackers and hit Angel Rivera-Figueroa, who checked himself into the hospital that night, claiming he was shot by someone who tried to rob him on the Mulberry Street bridge.

Deputy District Attorney Steve Zawisky says one of the other suspect turned Johnson in.

"The one individual who was involved in the case and got shot during this robbery and one of the first who was arrested, he did not indicate to the police that Johnson was involved," Zawisky said. "However later, based on the information we received, we determined that he was in fact involved in this. So we didn't receive that information until recently."

The other five suspect are scheduled to stand trial next month.

Johnson is being held in the Lancaster County Prison. He has been suspended without pay from his guard job in Dauphin County.
