Sheriff's homicide detectives were searching for a documented gang member in connection with a late-night, fatal stabbing outside a Laguna Niguel pub.
Craig Tanber, 37, was tied to the murder of 22-year-old Shayan Mazroei of Laguna Niguel, according to the Orange County Sheriff's Department.
Mazroei was stabbed in his upper body during a fight in front of Patsy's Irish Pub before 12:15 a.m., deputies said. His attacker fled.
The victim was taken to the hospital, where he was pronounced dead. His friends described him as friendly and said he would not have picked a fight.
Deputies said evidence collected at the scene led them to believe that Tanber was responsible for the killing.
"Tanber is a documented gang-member with a significant criminal history and should be considered armed and dangerous," deputies said.
He is described as a white man who is 6 feet 1 inch tall, weighing 190 pounds. He has brown hair, hazel eyes and numerous tattoos covering his body.
