Authorities issued the statewide Amber Alert on Saturday afternoon.
In an interview the girl's father, Wesley Mathews, said that he told Sherin to stand near a large tree near his home early that morning because she would not drink her milk. When he returned 15 minutes later to check on the girl, she was gone.
The dad then didn't notify police that his daughter was missing until about five hours later, according to the affidavit.
Sgt. Kevin Perilich told the Houston Chronicle that 37-year-old Mathews allegedly told police that he made his daughter stand by a tree in the alley near their home because she wouldn't finish drinking her milk.
Officers from the Richardson Police Department have sent out a Child Abduction Alert and are searching for 3-year-old, Sherin Mathews.
The charge is abandoning or endangering a child. Matthews' bond is set at $250,000. There's still no sign of Sherin Mathews.
Wesley Mathews told police that coyotes had been spotted in the alley where he left his daughter. The unidentified neighbor said, the couple thought they could "help another little one" who didn't have a family, so they adopted. She has brown eyes and black hair. They have also arrested the girl's father. The search continues for young Sherin, who was last seen by her father wearing a pink top, black pajama bottoms and pink flip flops, police said.
Police have described her as Asian, 3 feet tall and about 22 pounds. He said, "God will reward you".
