Gang members shot and wounded fourpeople, one critically, in two south central Los Angeles attacks early Tuesday after a hot holiday weekend left a police officer and two other men dead.

A man was critically wounded and a woman suffered gunshot wounds to the leg when two gang members stole their car at 12:20 a.m., Sgt. Robert Bloomer said. Witnesses said the car was a sedan made in the 1950s.Both victims were taken to Los Angeles County Martin Luther King Jr.-Drew Medical Center.

About the same time and just over a mile to the south, a man was seriously wounded in a gang shooting, Bloomer said. He also was taken to the medical center.

At 4 p.m. Monday, a 22-year-old man was shot dead while chasing a gang member who had robbed his three friends.

The man, whose name was withheld until his family could be notified, was running after the robber in west Los Angeles when the thief turned and fired, Lt. Rich Malony said. The man died hours later at Kaiser Foundation hospital, where one of the robbery victims was treated for a gunshot wound to the leg.

Just after midnight Monday, two gang members walked up to a group of people standing near the Memorial Coliseum and opened fire, detective Bernie Skiles said.

Robert Myers, 31, was struck in the head and Clairborne Lejohn, 22, in the leg, Skiles said.

Myers was pronounced dead at County-USC Medical Center, Skiles said. Lejohn was in stable condition at California Medical Center. Neither man was believed to be a gang member.
