A southwestern Michigan woman convicted of murder in the death of her daughter on the girl's fourth birthday has been sentenced to life in prison.

The Kalamazoo Gazette reports Daveeta Walker was sentenced Monday after a jury in September convicted her of murder and other crimes. Kalamazoo County Chief Assistant Prosecutor Carrie Klein says Walker "more than earned" the sentence.

On the witness stand, Walker denied abusing her children. She says she told Kalamazoo police a different story about "whooping" Kharisma Richardson because she felt threatened.

Kharisma was found dead in March. Walker says the child was in someone else's care the previous night. There were scars, bruises and burns on Kharisma. Her death was due to complications from multiple injuries.
