A 24-year-old North Hollywood resident pleaded not guilty to murder charges on Feb. 7 for the stabbing death of a passenger on Jan. 13 on the Metro Red Line subway in East Hollywood.

The defendant, Angelo Correia, remains in custody in lieu of $1 million bail. He is scheduled to next appear in court on March 10 for a meeting to set a preliminary hearing date. The stabbing occurred at approximately 9:18 a.m. on Jan. 13 as the train was pulling in to the Santa Monica/Vermont subway station. Witnesses reported seeing a suspect walking between cars, singing loudly. When the suspect approached the victim — Jose Velazco-Alvarado, 34 — a brief altercation ensued. The suspect then pulled out a knife and stabbed Velazco-Alvarado in the neck.

The suspect exited the subway and fled on foot. Paramedics took the victim to a hospital, where he was pronounced dead.

Los Angeles County Sheriff’s Department investigators received an anonymous tip on Jan. 17 that led to the identification of Correia. The incident had been recorded by surveillance cameras on the subway, which helped link the suspect to the crime.

The homicide was the second to occur on the Metro Red Line since it opened in 1993.
