Three men were charged with murder yesterday in the fatal shooting of a 33-year-old Fairfax County convenience store worker during an armed robbery Tuesday. Police said one suspect had shot himself in the leg as he climbed into the getaway car.

Fairfax County police said they identified the three suspects after receiving a tip minutes after the late night shooting at the Shell Food Mart at 5757 Seminary Rd. in the Baileys Crossroads area. Woo Il Pak of 110 N. Wayne St., Arlington, was shot fatally in the abdomen and his wife, Sunye, 30, suffered a gunshot wound in the thigh and is in satisfactory condition at Fairfax Hospital, according to hospital officials.

Police identified the three suspects as Steve T. Wright, 22, and his cousin, David B. Wright, 21, both of Baltimore, and Anthony McGlothen, 34, of 6198 Edsal Rd., Alexandria.

David Wright, who police say fired the shots that killed Pak and wounded his wife, was arrested at a Baltimore hospital where he is being treated for the gunshot wound in his leg, according to police.

Police said Steven T. Wright, who they believe was the lookout man, was arrested in Baltimore and is being held at the Baltimore City Jail.

Police said they believe McGlothen was the driver of the getaway car. He was arrested at home and is being held at the Fairfax County jail in lieu of $250,000 bond.

The Paks had moved to the United States from Korea and had been working at the convenience store to help finance the expenses for bringing their two young children to the United States later this spring.

Woo Il Pak died early Wednesday morning, five hours after he was airlifted from the store to Fairfax Hospital.

Fairfax County police said they do not know how much money or property was taken during the robbery.

"We got some information [on the suspects] from a citizen who called within minutes of when the robbery occurred," said Officer Connie Curran, a police spokeswoman. "About 20 minutes later, our people were able to locate the car . . . and determine who the three occupants were."
