A Long Beach man was convicted today of second-degree murder for stabbing another man to death with a screwdriver, the Los Angeles County District Attorney’s Office (LADA) announced today.

Arturo Ruiz Torres, 33, was harassed by an unknown man on November 23, 2013, according to a court testimony. He then mistook 50-year-old Anthony Ramirez, who was riding by on his bike, for the man who was harassing him and subsequently stabbed Ramirez three times with a screwdriver, the LADA said.

Torres then fled the scene and left the screwdriver lodged in Ramirez’s body, said prosecutor Lindsay Kurtis.

“Torres was with a group of friends when the attack occurred,” said LADA spokesman Richard Santiago. “A witness led police to one of the friends in his group, and that friend identified him as the attacker and later testified at the trial.”

Torres faces 16 years to life in state prison, and is scheduled to be sentenced on January 29.
