A Missouri mother has been charged with child abuse and murder after police said she let her boyfriend rape her 2 year infant, resulting in the child’s death.

Prosecutors in St. Charles County on Monday released details about how 25-year-old Jessica Lynn Howell sent text messages to her boyfriend, Jordan Lafayette Prince, indicating that she was willing to let him have sex with her daughter even though she knew he had previously been convicted for sexual abuse of a minor.

“In those text messages, she suggested and encouraged some unspeakable things,” St. Charles Prosecuting Attorney Tim Lohmar told KTVI. “It is very, very disturbing.”
