A federal jury has convicted a 26-year-old man on all counts in the killing of a former member of Delta Force and a retired Army warrant officer whose bodies were found in a wooded training area on Fort Bragg in 2020. Court records state Kenneth Quick caused the death of former Delta Force soldier Billy LaVigne “through the use of” a firearm in a cocaine deal gone bad. The case was featured in The Fort Bragg Cartel, the best-selling book by Seth Harp.
