A 3-year-old from Texas has been missing for three days since her father sent her out alone to an alley at 3 a.m. -- her punishment, police say he told officers, for not drinking her milk. Sherin Mathews, a special-needs toddler last seen early Saturday morning in her family's back yard in Richardson, a northern Dallas suburb, is thought to be in grave and immediate danger. Her father, Wesley Mathews, was arrested and charged Saturday evening with abandoning or endangering the girl. He was released Sunday night on a $250,000 bond.
