Texas police are searching for a 3-year-old boy who disappeared Wednesday afternoon when he chased a neighbor’s dog into the woods.

Christopher Ramirez’s mother believes her son was kidnapped, but the Grimes County Sheriff’s Office says they’ve found no evidence to say the boy was abducted, KHOU reported.

Araceli Nunez said she only took her eyes off her son for a moment and began calling his name as soon as she noticed he was missing at about 2 p.m. Wednesday, but she never got a response.

Grimes County Sheriff Don Sowell said nearly two dozen agencies are involved in the search for the toddler, including the FBI. K-9s are on the scene, and helicopters have been flying overhead.

Family members told investigators that Christopher likes to play in vehicles, so searchers headed out over the Foxfire subdivision in Plantersville to search all the vehicles in the area.

Christopher was last seen wearing a bright green shirt, shorts, and red Mickey Mouse shoes. He’s about 3 feet tall and weighs about 45 pounds.

His mother said he speaks only Spanish but responds to his name, KAGS reported.

The dog the boy was chasing has returned home.
