SANTA MONICA (AP) - A gunman with an assault-style rifle killed at least six people in Santa Monica on Friday before police shot him to death in a gunfight in a college library, authorities said.

Police Chief Jacqueline Seabrooks told reporters the rampage began at a house in the coastal city before the gunman, dressed all in black, made his way to Santa Monica College.

Seabrooks said he killed two people in the house, which caught fire, two more people as he moved several blocks toward the campus, and then two more on campus.

He entered the library and fired on other people but didn t hit them, Seabrooks said.

Several students in the library reported hearing gunfire, and one witness said he heard a woman scream.

"The officers came in and directly engaged the suspect and he was shot and killed on the scene," Seabrooks said.

She identified the gunman as 25 to 30 years old and dressed all in black, wearing what appeared to be a ballistic jacket.

The campus was searched for a second shooter, and a man dressed entirely in black, with the words "Life is a Gamble" on the back of his sweatshirt, was seen being taken into custody by law enforcement officers. He did not appear to be wounded.

"We are not convinced 100 percent that the suspect who was killed operated in a solo or alone capacity," Seabrooks said.

All of this unfolded about 3 miles (5 kilometers) from where President Barack Obama was attending a fundraising luncheon.

Three women with gunshot wounds were admitted to Ronald Reagan UCLA Medical Center, said Dr. Marshall Morgan, the chief of emergency medicine. One died, another was in surgery, and the third was in serious condition but doing well, he said.

Three other women went to UCLA Medical Center Santa Monica with relatively minor injuries, Morgan said. One has shrapnel-type injuries and the two others had injuries not related to gunfire, he said.
