A Mississippi police officer apparently shot himself to death on an Interstate just hours after an investigation into charges he had sex with a teenager went public.

Jackson Mayor Chokwe Lumumba identified the officer as 29-year-old James Hollins.

Jackson Police Chief James Davis told media outlets the officer shot himself Monday afternoon on Interstate 220. Hollins apparently pulled over onto the side of the road and shot himself inside his vehicle.

A lawyer for the family of the 15-year-old girl told reporters Monday morning the officer had sex with the girl for six months and there are several videos of their encounters in his patrol car.

Attorney Lisa Ross called for an immediate investigation.

The Jackson Police Department a few hours later announced the officer was on administrative leave and an investigation had started. The officer was found dead a short time later.

The incident shut down I-220 for hours.
