A Metrobus driver was arrested Wednesday morning in connection with the 2010 killing of a handyman who died defending a Centreville family from home invaders, authorities said.

Stacy L. Reed, 42, of Manassas, was arrested at a Pentagon bus stop and accused of conspiring to commit a robbery, authorities said.

Reed is expected to make his initial court appearance at 2 p.m. today in the federal courthouse in Alexandria.

Jose Cardona, the handyman, was killed after he discovered two armed home invaders in the garage of the Centreville home in May 2010, according to court documents.

The men were waiting for the return of the home’s owner, who they believed kept proceeds from several Northern Virginia check cashing businesses inside his residence, according to court documents.

Reed is accused of conspiring with the two men — Tashaik Champean, of Suitland and Reynard Lazaro Prather, of Oxon Hill — to commit the robbery, according to court documents.

Caroline Lukas, a Metro spokeswoman, said Stacy Lorenzo Reed started with Metro on August 19. The warrant for his arrest was issused this week, a Metro official said.

Reed would be put on paid leave pending the outcome of the case, Lukas said.

Reed was driving a 9E bus, according to Lukas, and was at the end of his line. After he pulled into a bus bay at the Pentagon and all the riders were off, the Metro official said, U.S. Marshals at the door of the bus asked him to step off. He did, and was arrested wthout incident.

Reed’s arrest comes less than a week after Champean pleaded guilty to conspiring to commit murder and robbery in connection with the incident. He faces a maximum penalty of life in prison.

In February, Prather pleaded guilty to conspiracy to commit a robbery, use of a firearm in a crime of violence and use of firearm in a crime of violence causing death. He was sentenced to 30 years in prison in June.
