Mateo Villegas was last seen Friday around 7:15 p.m. near Germann Road and Ranch House Parkway, according to DPS. The agency said Villegas has a medical condition that causes him to function at the developmental level of a child between 10 and 13 years old, a factor that makes his disappearance especially urgent.

Authorities described his clothing and belongings in the hope that community members will recognize him: a dark baseball cap, a black shirt with a Mexican restaurant logo on the back, and black shorts. He was also carrying a skateboard and a backpack.

SAFE Alerts are Arizona's system for rapidly spreading word about missing people who are 65 or older or who have dementia or developmental or cognitive disabilities. The alerts replaced the state's Silver Alert program. DPS said a SAFE Alert was previously issued for Villegas in a nearby area in March.

Anyone with information about Villegas's whereabouts is urged to contact local law enforcement immediately. Community members in the southeast Gilbert area are asked to check their surroundings and review any doorbell or vehicle camera footage from Friday evening that might show him.
