WEST VALLEY CITY — The mother of a 9-year-old boy found riding his bike on I-215 over the weekend has been cited with reckless endangerment, police said.

The boy was picked up by a concerned citizen who spotted him riding his bike along the freeway about 11:30 p.m. Friday. He was unable to give his name or address because of a speech impediment or other impairment, and spent the weekend at the Christmas Box House while police located and interviewed the mother.

The boy's mother, Reyna Perez, 25, was cited for reckless endangerment, a class B misdemeanor, because of how long she waited to report her son missing, said West Valley Police Sgt. Jason Hauer.

Investigators determined the boy left his home about 5 p.m. Friday, but Perez didn't contact police until noon the next day.

"We're talking about a 17- to 18-hour amount of time where this mother knew her child was missing and didn't contact law enforcement," Hauer said. "Our suggestion to anyone who comes into this situation is to contact law enforcement sooner than later."

A hearing took place Tuesday to determine when the boy will be released to his mother, Hauer said. Investigators didn't find any other concerns in the home that would prevent the child from returning.
