ST. CHARLES COUNTY, Mo. (KSDK) - The St. Charles County Prosecuting Attorney's Office charged a 25-year-old O'Fallon woman for allegedly offering up her four-month-old daughter to her boyfriend so he could engage in sexual activity with her, resulting in the child's death.

St. Charles police officers responded to a report of an unresponsive four-month-old child in the 3600 block of Fremont Drive on December 3, 2012. The child, identified as Ashlynn Peters, was flown to an area hospital for treatment where she died.

An autopsy on December 5 revealed Ashlynn died from asphyxiation and was also the victim of blunt force trauma to the head and various parts of her body. The child was sexually assaulted, leaving rectal tears and lacerations.

Authorities interviewed Jordan Prince, who was watching the infant while the baby's mother slept. Prosecutors said Prince told police he became frustrated because the baby would not stop crying, choked the child and then left her on a loveseat. Prince came back an hour later and found the child unresponsive.

Jordan Prince was charged with first-degree murderin December 2012 and indicted in April 2013 for forcible sodomy and child abuse.

Investigators learned the girl's mother, identified as Jessica Howell (also known as "Jessica Peters"), knew her boyfriend had previously been convicted for sexual offense against a minor. Howell allegedly engaged in a series of text messages with Prince on September 15 and September 16, 2012, suggesting a willingness to allow him to have sex with her daughter.

Jessica Howell was charged with second-degree murder and remains incarcerated at the St. Charles County Adult Detention Facility on $1 million bond.
