SAN LEANDRO, Calif. – Three people were killed and three others wounded when at least two gunmen opened fire as people left a party at warehouse early Sunday, authorities said.
The gunmen started shooting as a group of people walked out of the building around 1:20 a.m., San Leandro police Sgt. Doug Calgano said.
Three people were pronounced dead at the scene. Police did not know the condition of the three wounded people. The names of victims have not been released.
At least 100 people attended the party, which had been advertised on the Internet, Calgano said. He was not aware of a permit being issued for the party, which would have been required for a gathering of that size.
As the shooting began, many of the partygoers fled.
"Obviously it was a chaotic scene," Calgano said.
The gunmen were armed with semi-automatic handguns, but police have not determined how many shots were fired. Investigators were trying to establish if the gunmen had attended the party, or arrived as people left the party. It was not clear if the gunmen were in a vehicle or on foot when they opened fire.
No arrests have been made, and police have not determined a motive.
