Last month, Lisa Knight’s husband Patrick, who was wounded in the shooting, sued his former inlaws for damages and the loss of his wife. Knight claimed that the Merhige’s knew of their son’s “dangerous propensities” and failed to protect their relatives during the Thanksgiving get-together from him.

A similar suit making the same claims was filed by the Sittons.

Merhige, who has pleaded not guilty to the killings, was captured in the Florida Keys after a massive manhunt. He’s scheduled to go trial this January and could receive the death penalty if convicted.
