In July 2010, Herbert Glass, 58, and his 42-year-old wife, Lynette Williams, were last seen alive on July 7. Their families reported them missing on July 9, and construction workers on the Interstate 10 twin-span over Lake Pontchartrain discovered both bodies floating in the water that same day. Both victims had been bound with duct tape and shot in the head. The couple’s Toyota Camry had been found burned off an interstate exit near Pearl River on July 8, and investigators believed the killings occurred on the south shore before the bodies drifted into the lake.

Relatives told police Glass had recently received a significant insurance settlement after his mother’s death, a detail family suggested could relate to motive. The case went cold for years, leaving many unanswered questions about who attacked the couple and why.

Does anyone have information about Herbert Glass or Lynette Williams, their movements in July 2010, or the burned Camry found near Pearl River?
