The mother of a 2-year-old girl found dead in a Pennsylvania ravine last month has been charged with killing her.

Online court records show Allegheny County police obtained an arrest warrant Tuesday for 26-year-old Adriene Williams, of Wilkinsburg, on charges of criminal homicide, endangering the welfare of a child, tampering with evidence and abuse of a corpse.

Her toddler daughter, Adrionna, was discovered dead in a neighboring suburb about 40 minutes after her family reported her missing June 14.

It wasn't clear if Williams was in custody. She couldn't immediately be reached for comment Tuesday.
