Mary Amelia Woods, 28, of 612 Miller Road, is in jail after an investigation determined her actions contributed to the death of her infant son, according to a news release from Sumter Police Department.
Woods is charged with homicide by child neglect and is being held at Sumter-Lee Regional Detention Center.
Police and Department of Social Services were called to the home on Oct. 8, 2016, after a 5- to 6-month-old infant was found unresponsive.
A warrant indicates the mother rolled over on the child, suffocating it while sleeping. According to the warrant and a statement given by the suspect, she was intoxicated at the time.
Woods turned herself in Thursday morning without incident.
