A Baltimore man and an Alexandria woman have been arrested and charged with abducting a 30-year-old Northern Virginia woman and driving her to Maryland where she was raped, robbed, beaten, burned with cigarettes and left to die along I-95, the FBI reported.

Lonnie M. Richardson, 25, of Baltimore, and Andrietta R. Bruton, 20, of 8 S. Van Dorn St., were charged with kidnaping and the interstate transportation of a stolen vehicle, the FBI said.

"The motive was apparently money," said Maryland State Police Sgt. Roger D. Cassell. "They got $5." He described Bruton as "very pregnant."

Andy Manning, an FBI spokesman, said Richardson was arrested Wednesday after he was stopped by Officer John Tiell for driving a car without headlights. Although the car bore Pennsylvania plates, Manning said a check of the vehicle identification number showed it was registered to the abducted woman.

Bruton was arrested early yesterday at a Baltimore residence, Manning said.

The woman was abducted at gunpoint about 9:30 p.m. Sunday by a man and a pregnant woman, both of whom were armed, as she walked from her car to her home in Alexandria's West End, police said.

The couple forced the woman to return to her car, handcuffed her and drove around Washington, Baltimore, sections of Howard County and along I-95, police and the FBI said. They said that during the drive, the pregnant woman repeatedly burned the victim with cigarettes.

The woman was then driven to a rest stop near Laurel where she was raped, struck several times with a gun and left for dead, authorities said. She pretended to be unconscious, then later stumbled to an attended area to seek help.

The victim was treated at Greater Laurel-Beltsville Hospital for head cuts and was later released, hospital officials said.

State police are investigating the abduction. Richardson and Bruton were being held last night in Baltimore awaiting bond hearings.

A passenger who was in the car with Richardson when he was stopped, David N. Lucas, 20, of Baltimore, also was arrested, charged with unauthorized use of a vehicle and later released, according to police.
