The Moreno Valley station of the Riverside County Sheriff’s Department said it learned of the attack – which was captured in its entirety on the city-wide camera system – on Sunday night. “The video clearly depicts three male juveniles being attacked without provocation, while many onlookers stood by, without intervening on behalf of the victims,” the Sheriff’s Station stated on Facebook. The victims were all between the ages of 14 and 15, according to the statement. Video of the attack was also posted on a Facebook community page called Moreno Valley Matters. Investigators determined the encounter took place about 8:15 p.m. Saturday night at the skate park located at Frederick Avenue and Cottonwood Street. Two suspects – 35-year-old Robert Lee Aaron III and a 17-year-old boy – were arrested during the serving of a search warrant overnight, the Sheriff’s Station said. Another 17-year-old boy is still being sought as well as other “persons of interest.” Deputies said they seized evidence, including a firearm, during the search. Aaron was booked on several charges, including assault with a deadly weapon and contributing to the delinquency of minors. The 17-year-old was booked into a Riverside juvenile hall facility on felony assault and conspiracy charges. No motive for the attack was released.
