The day after her son was reported missing, then found dead, a 20-year-old Missouri mother has been charged with 2nd-degree murder in the boy's death.

FOX News Radio's Dave Anthony reports:

Little Tyler Dasher was found dead Tuesday near a St. Louis cemetery, hours after his mother reported the 13-month-old missing, saying she overslept and when she checked on him...

(Fitch) "She looked into the bed and found that he was gone."

Tuesday night, St. Louis County Police Chief Tim Fitch said...

(Fitch) "We've talked to the mother and the father, and they've both been cooperative with us."

But as they searched the house...

(Fitch) "There was nothing that the investigators saw - like a broken door, broken window, anything like that - would lead them to believe there was forced entry."

Wednesday morning, Tyler's mom, Shelby Dasher, was taken into custody.
