Shortly before 6 p.m., a woman was driving a Toyota sedan in the 4100 block of Mariban Court and was being followed by a white Cadillac, said Sterling Clifford, a city police spokesman.
Near the intersection of 10th Street, Clifford said, someone in the Cadillac fired several shots into the Toyota, striking the driver and passenger. One bullet, Clifford said, struck a woman sitting on her back porch nearby.
The Cadillac sped away, while the Toyota drifted to the side of the street and came to rest against the curb, Clifford said.
The woman, identified by police as Sandy Howard, 23, of the 2900 block of Carver Road, was pronounced dead at Maryland Shock Trauma Center.
The passenger, Dontey Sims, 22, and the woman hit by a stray bullet, Tiffany Moore, 28, of the 4100 block of Mariban Court, were each taken to Shock Trauma. They were in good condition last night, police said.
Police said at least one witness was taken to police headquarters for an interview and that it was not immediately known whether the driver of the Toyota was the intended victim of the gunman in the Cadillac.
