Gunmen open-fired, with semi-automatic weapons, shortly after a party let out Saturday night/early Sunday outside a warehouse in San Leandro, killing three people and wounding three others. The party, publicized on Facebook as a Tattoo Party for tattoo enthusiasts wanting to mingle and show off their tattoos, apparently drew hundreds to the semi-remote, industrial location. From the sound of it, the three fatalities were among three people who may have known each other: 19-year-old S.F. State student and S.F. resident Shanice Kiel, 16-year-old Lanisha Worthington, and 23-year-old Josh Alfred of Oakland.

Kiel's father has made a plea for witnesses to come forward and speak to police, or to call the San Leandro Police tip line at 510-577-3278 with any information. "We know there were a lot of people there and if you know or saw something, please call San Leandro police," he says. "If I can get some justice for her, my baby can rest in peace."

Police are still trying to figure out who rented the space and threw the party -- the Facebook posting has been removed -- and it doesn't sound like they have a lot of leads on the gunmen, who may or may not have been guests at the party.
