2 suspects arrested in deadly shooting of Riverside teen
Two suspects were arrested in connection with the deadly shooting of a teenager in Riverside.
They were identified as Francisco Gallegos, 20, and Bryan Torres-Arroyo, 21, according to the Riverside Police Department.
On May 28, 2023, police responded to a shooting in an alleyway near Chicago Avenue and Linden Street around 5:13 p.m.
Officers found two teen boys, a 17-year-old and an 18-year-old, with gunshot wounds. Both were transported to the hospital.
The 18-year-old, later identified as Isaiah Arviso of Riverside, died from his injuries. The other teen survived. Both suspects fled the scene before police arrived.
'Detectives initially had a limited suspect description and exhausted all available leads, as this shooting appeared to be gang-related,' Riverside police said.
Following an extensive investigation, detectives eventually identified Torres-Arroyo and Gallegos as the primary suspects.
Search warrants were served at their residences and on July 11, both were arrested for murder. The investigation remains ongoing and no further details were released on the case.
