A convicted serial killer from New Jersey has been indicted in a fourth murder.

Khalil Wheeler-Weaver is accused of strangling 15-year-old Mawa Doumbia, of Newark.

Police say that Wheeler-Weaver asked Doumbia online for a sexual encounter in 2016.

Doumbia was reported missing in 2016. Doumbia’s remains were identified last year after they were found in a vacant building in Orange in 2019.

Wheeler-Weaver is also facing sexual assault, endangerment and body desecration charges.

Wheeler-Weaver is already serving a 160-year sentence for the murders of three other women and the attempted murder of a fourth.
