Police track down man suspected of killing victim with one punch at Trolley station

A 27-year-old man suspected of punching another man in the face at a trolley station, resulting in his death a week later, was taken into custody on Tuesday.

The assault occurred at approximately 2:24 p.m. on March 18, when Javier Teran-Pascasio, 38, was punched once in the face and collapsed to the ground at the 12th & Imperial Transit Center, according to the San Diego Police Department.

San Diego Fire-Rescue Department personnel responded to the location, where they treated Teran-Pascasio before taking him to a hospital.

Police said his injuries were the result of the assault and that detectives were initially investigating a battery offense.

The suspect, identified as Kenny Dunn, was spotted the following day by San Diego Metropolitan Transit System personnel, who requested SDPD officers come to the scene, police said.

No witnesses were able to positively identify Dunn as the suspect at the time of the initial arrest, police said, and Dunn, also known as Kenny Corzine, was released from custody.

Detectives located Dunn on Tuesday in the 1300 block of East 30th Street in National City, two blocks west of North Second Avenue, where he was arrested in connection with the assault.

“Teran-Pascasio never regained consciousness, and on March 25, 2026, he died as a result of his injuries,” police said in a statement.

The relationship between Dunn and Teran-Pascasio, if any, remains unknown.

Anyone with information about the case was urged to call the SDPD Homicide Unit at 619-531-2293. Tipsters who prefer to remain anonymous can call Crime Stoppers at 888-580-8477.
