ST. JOHN, Mo. (AP) — Missouri woman has been charged in the death of her 4-month-old son who was left alone for five hours with two other young children.

Twenty-one-year-old Blessing Barlee was arraigned Monday on three felonies, including child endangerment resulting in the death of Micah Lee Stringfellow. Barlee is accused of leaving Micah and a 1- and 4-year-old alone from last Wednesday night into Thursday morning.

St. John Police Capt. Bob Connell says it’s unclear where she was during that time. He says a tow truck driver who dropped Barlee off at her home called 911 when she ran outside with the baby in her arms. Connell says there was no obvious sign of trauma to the infant, whose cause of death hasn’t been determined.
