SANTA MONICA, Calif. -- Officials say a man who went on a shooting rampage in Santa Monica, Calif., began the rampage by killing his father and brother.
Meanwhile, a police spokesman says five people, including the gunman, are dead. Police said earlier that seven people were killed, including the gunman.
Two officials briefed on the investigation say the killings Friday began as a domestic violence incident.
The officials spoke on condition of anonymity because they were not authorized to publicly discuss the case.
The officials say the first two victims were the brother and father of the gunman. They were found in a burning home about a mile from the Santa Monica College campus where the gunman was killed.
Police say the gunman killed two more people and injured several others before officers fatally shot him in the college library.
Santa Monica 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.
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 and was later released.
All of this unfolded about 3 miles from where President Obama was attending a fundraising luncheon.
