A mother is under arrest after allegedly allowing her boyfriend to rape her infant child, causing the child to die.

Jessica Lynn Howell, 25, of St. Charles County, Missouri, was arrested in connection with the death of her four-month-old daughter, Ashlynn Lilith Peters. Ashlynn died December 3, 2012.

Originally Howell was not charged as she claimed innocence in the attack, but prosecutors say text messages between Howell and her boyfriend Jordan Lafayette Prince are conclusive and damning.

Prince has been in custody awaiting trial for the murder of Ashlynn Lilith Peters for several months, and has a past history of sexual abuse which Howell admits to knowing. In an apparent attempt to spice up their relationship, Howell offered to allow Prince the opportunity to sexually molest her daughter.

According to the local reporting of St. Charles Prosecuting Attorney Tim Lohmar said:
In those text messages she suggested and encouraged some unspeakable things. It is very, very disturbing.
While the text messages between the two suspects have not been released, the official police report tells a gruesome story about the condition little Ashlynn was found:
Ashlynn was sexually assaulted causing multiple tears to her anus, a massive laceration to her rectum with massive hematoma in the area of the pelvis. The injuries to the anus and rectum of Ashlynn were sufficient to eventually cause her death even without strangulation.
Beyond the rape that physically killed the child and caused her to stop breathing, she was also beaten:
Ashlynn was also the victim of blunt force trauma to the left side of her head causing a laceration to her ear and a hemorrhage near her skull.
Jessica Lynn Howell and Jordan Lafayette Prince are both currently in custody awaiting trial.
