Lafourche Parish Sheriff announced a former Lafourche Parish resident has been charged with aggravated incest and sexual battery of a family member. William Patrick Gilliam (age 44) of Duenweg, Missouri, is currently in custody in that state.

In May 2017, juvenile detectives began an investigation after receiving a complaint about a family member having been sexually abused by Gilliam over the course of several years. The initial incident occurred approximately six years ago in Raceland, where Gilliam resided at the time. Through investigation, detectives learned Gilliam had inappropriate sexual contact with the victim in Lafourche Parish and other jurisdictions. Detectives obtained warrants for Gilliam’s arrest for Aggravated Incest and Sexual Battery (Forcible Fondling).

In late May, detectives learned Gilliam was in custody in Jasper County in Missouri where he faces additional charges. Detectives believe the juvenile is the sole victim of Gilliam’s abuse.

Due to the nature of the charges, no further details will be released at this time.
