The boy used a restroom at Hunter Park during the night since he has been living with his mother and sibling inside a car nearby, according to police. He told his mother about the assault when he returned to their car, police said.

Officers responded to the reported sexual battery around 1 a.m., and they found Funk still at the park, police said. Detectives with the Riverside Police Department’s Sexual Assault – Child Abuse Unit have since taken over the investigation.

According to police, the boy’s family has received temporary transitional housing and referrals to outreach services from the city’s Office of Homeless Solutions and Public Safety Engagement Team.

The investigation remains ongoing.
