Two of the victims are in "extremely critical condition," according to San Bernardino Police spokesman Cap. Richard Lawhead. The numbers were revised after an initial report of 10 people shot, Reuters reported Saturday.

A 17-year-old boy who is in critical condition was the youngest victim, police said.

Police do not have suspects or a motive in the case yet, and said witnesses were not cooperating.

Lawhead said the shooting took place in a common area of the complex and all the victims are believed to be adults.

The incident occurred around 10:45 p.m., Lawhead said. Officers responded and found “at least 10 victims down,” Lawhead said.

Alysa Marie, who lives near the apartment complex, told CNN she heard 15 to 20 gunshots fired in rapid succession.

"My brother-in-law could hear bullets flying past our house, he was outside at the time of the shooting," Marie said. "About five minutes later the helicopter was circling around our street, talking on the loud speaker saying to put down the weapons, for the people who were on the ground to get up and get to safety and to let the law enforcement do their job."

Another neighbor, Eduardo Rivas, told CNN he heard multiple shots from his house a block away.

"I heard around four shots, then what sounded like a motorcycle speeding off, after that just a continuation of gun shots," Rivas said.

There is no suspect in custody, CNN reported.
