SAN JOSE — San Jose police are asking for the public’s help in locating a 6-year-old boy who went missing from his home Saturday morning.

The mother of Sergio Zepeda, who is autistic and non-verbal, said her son disappeared from their residence on the 2900 block of Rorty Drive in South San Jose about 9 a.m., police said.

“We’ve got a lot of resources out there looking right now for this missing juvenile,” said Officer Albert Morales, a San Jose police spokesman. “The sense we have right now is that he just wandered off. There’s nothing to suggest that there’s any foul play. But we’re increasing the size of the search area, and we need more eyes looking for him.”

Sergio is described as a Latino boy with brown hair, approximately four-feet tall and weighing 40 pounds. He has a red rash mark on the left side of his lip. He was last seen wearing a black “Super Mario Brothers” T-shirt and blue jeans.

If you think you’ve seen the boy, police ask that you call 911 or the department’s missing person unit at 408-277-8911.
