(KMOV) – Murder charges have been dropped against a woman initially accused in the death of her 18-month-old son found in a trash bin in south St. Louis in May, 2011.
Melissa Jackson, 30, was scheduled to go on trial Monday for first-degree murder and felony abuse of a child after the body of her son, Marquell Jackson, was discovered in a dumpster at an apartment complex on S. Jefferson Ave. Her attorney received notice Monday all charges have been dropped.
Preliminary autopsy results indicated Marquell was beaten. His injuries included trauma to his brain, ligature marks with corresponding injury to the inside of his neck, multiple rib fractures and multiple liver lacerations resulting in internal bleeding.
Authorities said his death was caused by someone striking or strangling him. His mother pleaded not guilty to the charges. She spent about 10 months in jail before being released on bail.
According to Melissa Jackson’s attorney, a police deposition revealed one of her ex-boyfriend’s admitted to killing the boy and dumping his body. But the attorney said police never pursued charges against the man because his statement was never shared with homicide detectives.
Susan Ryan, spokeswoman for St. Louis Circuit Attorney Jennifer Joyce, would not explain why the charges were dropped. St. Louis City police Spokeswoman Schron Jackson said an officer might have compromised the case by not sharing information with homicide detectives.
“The department was disappointed to learn that an officer had information critical to the investigation and did not share it with homicide detectives,” she said.
Jackson said an internal affairs investigation is being launched in the case.
