A mom on a school has been killed by a stray bullet after shouting at her kids to run during a gang shootout in her San Francisco Bay Area neighborhood .

Investigators say a gunbattle apparently broke out as Pierce , a human resources employee at Kaiser Permanente , was heading home after picking up her kids from school . Witnesses say up to 50 shots were fired . The newspaper reports that two people possibly tied to the fight , a teenage boy and a man , were wounded but expected to survive . No arrests have been made . A contractor working at Pierce 's home told SFGate that he was inside working when he heard the gunfire . He said he saw Pierce 's children running around the side of the home and then hide . The family was walking home on the 2800 block of Chestnut Street ( pictured ) when a confrontation between two groups erupted further north . Witnesses say up to 50 shots were fired . He said he grabbed them and tried to shield them from seeing their mom 's body . 'Now they do n't have their mom . That 's sickening , ' he said . 'That 's very crazy . Who are these crazy-a** people ? She was n't involved in anything ! ' Pierce , who had plans to marry , also leaves behind a one-year-old son who was not there during the shootout . Lt. Roland Holmgren , with the Oakland Police Department , told Pix 11 said it was all connected to a violent gang feud in the neighborhood . 'Senseless gun violence and at the end of it a woman who has nothing to do with it , who is doing nothing more than trying to get her children to safety loses her life and the children lose their mother , ' Holmgren said . No arrests have been made .
