Former boyfriend of missing teen's mother to be charged in disappearance

COLUMBIA, SC (WISTV) - The Richland County Sheriff's Department plans to charge the former boyfriend of a missing teen's mother with kidnapping the teen.

Richland County Sheriff Leon Lott says the department has court documents allowing Grant to be charged with kidnapping in connection with Gabrielle Swainson.

The 15-year-old disappeared from her home in August. Swainson's mother dated Grant.

In January, a federal jury convicted Grant on charges he possessed ammunition as a convicted felon.  Richland County investigators working on Swainson's case found the ammunition in Grant's home.

Since then, investigators have  been searching for evidence connecting Grant with Swainson's disappearance.  Detectives found Swainson's hair in Grant's home after obtaining a search warrant, and police found her blood on duct tape near his property.

Grant has been held in federal custody at Lexington County Detention Center. He was scheduled for sentencing on the federal conviction in April.

Sheriff Lott says grant will be taken into custody Friday for a 2:30 p.m. bond hearing.
