Long Beach, CA — Detectives with the Long Beach Police Department’s Sex Crimes Detail have arrested a suspect in connection with a violent sexual assault that occurred early Tuesday morning, and they believe there may be additional victims.
The suspect, identified as 29-year-old Alvin Marbra, who is experiencing homelessness, was taken into custody on the afternoon of July 1, 2025. Authorities believe he is responsible for a brutal attack that took place just after 2:30 a.m. near Alamitos Avenue and 4th Street.
According to investigators, a female adult victim was walking in the area when Marbra allegedly approached her, physically assaulted her until she lost consciousness, and then sexually assaulted her.
Using nearby security camera footage, detectives were able to track Marbra’s movements. He was located later that day around 12:45 p.m. near 4th Street and Cherry Avenue and was arrested without incident. He was booked into the Long Beach City Jail on multiple felony charges, including rape, assault with intent to rape, and assault with a deadly weapon. His bail was set at $100,000.
“This alarming criminal act is deeply concerning, and the response of our officers and detectives underscores LBPD’s commitment to identifying and arresting individuals responsible for harming others,” said Long Beach Police Chief Wally Hebeish. “The work of the responding officers and handling detectives, coupled with our strategic use of technology and security video, allowed us to swiftly identify and arrest the suspect believed to be responsible for this heinous sexual assault.”
Investigators are now urging anyone who may have been victimized by Marbra or has information about similar incidents to come forward. They believe there may be additional unreported cases and are asking potential victims to contact the Sex Crimes Detail at (562) 570-7368.
The investigation remains ongoing.
