The 15-year-old boy, Jose Coatl, was seen leaving his basement-level apartment in the Bronx at about 7 p.m. April 2. Police said they’re “concerned” about the case, in part because of his autism diagnosis.

He was last seen wearing a red t-shirt and gray sweatpants, police said. He is described as being 5-feet-four-inches tall and about 120 pounds.
