On the morning of August 14, 2021, 29-year-old Lindsey Williams, a white woman, was found shot to death in the bedroom of her Marrero, Louisiana, home. Her 11-year-old son heard a noise, opened the door, and saw Williams’s ex-boyfriend Shawn Chiasson with blood on his hands. Chiasson used the boy’s cellphone to call 911, gave the operator the name Jake, reported that someone had been shot, then fled, leaving the child with his dying mother.

Investigators with the Jefferson Parish Sheriff’s Office identified 28-year-old Shawn Chiasson as the suspect and apprehended him two days later. Williams had been letting Chiasson stay in her home until he found a job despite not being a couple. Chiasson had a prior heroin-possession conviction that legally barred firearm ownership; he later admitted dumping the pistol along a canal bank in Westwego.

Chiasson pleaded guilty during trial to second-degree murder, being a convicted felon in possession of a firearm, and obstruction of justice. A judge imposed the mandatory life term for murder plus additional prison terms for the weapon and obstruction convictions to run concurrently. If anyone knew Lindsey or has information about her life or the events leading up to August 14, 2021, please come forward.
