He might have lost all his money at the card table, but he still had a chip on his shoulder.
A gambler who watched some $10,000 evaporate at a Colma casino early Monday — while also being accused of trying to steal chips off the table — allegedly followed a luckier card shark to Daly City and stabbed him with a sharpened screwdriver, prosecutors said Thursday.
William Don Ross, 30, of Brentwood pleaded not guilty Wednesday to attempted robbery and assault charges in connection with the attack, which followed five hours of unlucky card games at Lucky Chances.
Prosecutors said Ross followed the other card player in his car to Serramonte Plaza, where he attacked him in the parking lot and bit a witness who tried to intervene.
Surveillance cameras, along with witnesses, caught Ross “lurking between two cars sharpening a screwdriver on the asphalt,” San Mateo County District Attorney Steve Wagstaffe said.
He covered his head with a pink hoodie before going after the other card player, Wagstaffe said. Ross allegedly charged after the victim and stabbed him while screaming that he wanted his money back.
The hullabaloo began much earlier that morning, with Ross playing cards from 4 a.m. to 9 a.m. and losing between $6,000 and $10,000, prosecutors said. At one point, a fellow card player — reportedly the victim — accused Ross of stealing chips from the table, Chief Deputy District Attorney Karen Guidotti said.
The victim, who had better luck that morning, left the casino. Video surveillance captured Ross following the victim out of the parking lot, Wagstaffe said.
Guidotti said she didn’t know why Ross thought the money was his.
A witness came to the victim’s aid but was bitten by Ross, who drew blood, Wagstaffe said.
Bail was set at $100,000 on Wednesday. Ross remains in custody, prosecutors said. He is scheduled to return to court for a preliminary hearing April 10.
