Bobby Brown, a 30-year-old homeless man arrested Dec. 1, was indicted on four counts of attempted murder, five counts of assault with a deadly weapon, five counts of battery with seriously bodily injury and three counts of battery on a transit passenger, district attorney spokesman Brian Buckelew said.
He said the district attorney's office sought the indictment to "protect the victims and keep this case moving." The indictment bypasses a preliminary hearing in the case.
The grand jury issued its indictment Thursday, after hearing testimony by approximately 35 witnesses over five days, Buckelew said.
Brown is accused of stabbing a 41-year-old woman in the arm on a Muni train May 12; knifing an 11-year-old boy in the stomach on a Muni bus Sept. 1; stabbing two women who were walking in the Tenderloin on Nov. 14 and Nov. 26; and stabbing a 24-year-old woman twice with a corkscrew on a Muni train Nov. 30.
Police have said the stabbings were all random and unprovoked. All five victims survived, though the boy nearly bled to death.
A court-appointed doctor found Brown mentally fit to stand trial in January and his defense attorney later stipulated to the conclusion, Buckelew said.
Brown, who remains in custody on $5 million bail, is scheduled to be arraigned in San Francisco Superior Court at 9 a.m. Wednesday.
