TEXAS CITY, Texas -- Police and volunteers in Texas City are looking for a missing little boy who has autism.

The search is underway by ground, air and water with the help of the Texas Department of Public Safety.

They’re looking for 7-year-old Xavion Young, who was last seen at around 12:15 p.m. Sunday at the Costa Mariposa Apartments on Medical Center Drive in Texas City.

Authorities held a press conference with the media Monday afternoon. They said volunteers and officers have cleared two bodies of water near the apartment complex and they are working to clear a third.

The Galveston County Sheriff's Officers Dive team was called to search a pond nearby as the boy reportedly liked to feed geese that live in the pond.

The child's aunt tells KHOU 11 that Xavion unlocked a back door to their home and went out while his mom was in the bathroom.

Xavion is 3 feet tall, approximately 54 pounds and was last seen wearing only gray and white plaid shorts and black and blue Velcro shoes. Police say Xavion is nonverbal but will respond to his name.

If you see Xavion, you’re asked to contact the Texas City Police Department at 409-643-5720 as soon as possible.
