Police are concerned about the boy’s welfare because they say Martinez was angry at his mother.

“We do know there’s been some custody issues with the child, as far as any violence between the father and the mother, we’re not aware of that,” explained Denton Police Officer Shane Kizer.

Investigators are concerned that Martinez may have left the area with the child.

He has ties to Springfield, MO, Chicago and Mexico City.
