A Mocksville woman was charged with second degree murder Tuesday in an overdose death earlier this year.

Marissa Dell Johnson, 34, of Oak Street, is charged in the death of Ross Allen King Jr., 37, of Mocksville.

Johnson is already in the Davie Detention Center on other charges.

In addition to the murder charge, she is also charged with child abuse, sale and delivery of heroin, habitual felon, and assault with a deadly weapon in another overdose in Mocksville in April, reported District Attorney Gary Frank and the Mocksville Police Department.
