LAKE CHARLES - Lake Charles police say the mother of a 4-month-old infant who died earlier this month faces a charge of second-degree murder. Police say they are looking for the infant's father.

Police Chief Don Dixon says 25-year-old Courtney Morris was arrested Wednesday, and officers are searching for 40-year-old Larry Champ.

Dixon tells local media outlets police received a call July 14 about a dead infant. He said the child had no signs of injuries.

Dixon says the coroner's office did a routine sudden infant death investigation, performed an autopsy and submitted blood samples for analysis. He says the lab report, which came back Wednesday, showed that the baby had alcohol in his system.

Online jail record did not show an attorney for Morris.
