Police say they’ve arrested a Long Beach man accused of showing up to his ex-girlfriend’s home and shooting the man she was now dating.

Oscar Alejandro Chan, 41, was taken into custody Wednesday afternoon on suspicion of murder, illegally possessing a gun after being convicted of a felony, and illegal possession of ammunition, according to the Long Beach Police Department. His bail was set at $2 million.

Chan, according to police, arrived unannounced around 6:32 a.m. Wednesday to a home where his ex-girlfriend was living with her new boyfriend in the 6200 block of California Avenue, which is near Houghton Park.

Chan entered the home and got into a fight with the man before shooting him and fleeing the scene, police said.

Emergency crews rushed the wounded man to the hospital, where he died, police said. The man’s identity was not released pending notification to his next of kin, according to police, who described him as being in his 40s.

Police say they found Chan later that day at around 5:30 p.m. in the 11300 block of E Florence Avenue in Santa Fe Springs.

Detectives are still investigating the motive for the shooting, but they believe it stems from a dispute involving Chan, his former girlfriend and the victim, police said.

Police said detectives will present the case later this week to the Los Angeles County District Attorney’s office for filing consideration.
