On the evening of November 7, 2013, a family argument inside a Luling, Louisiana, home ended with three gunshots and the death of 42-year-old Stanley Robinson Sr. A woman who had been in the bathroom during the dispute found Robinson Sr. lying fatally wounded; paramedics pronounced him dead at the scene.

Investigators arrested his 20-year-old son, Stanley Robinson Jr., and charged him initially with second-degree murder; the charge was later reduced to manslaughter. Robinson Jr. was at one point found unfit to stand trial after a psychiatric evaluation that identified auditory hallucinations and religious delusions, and he was sent to East Louisiana Mental Health System for treatment and antipsychotic medication. He was later declared competent, but in December 2014 the St. Charles Parish District Attorney dropped the manslaughter charge for lack of sufficient evidence. The sheriff’s office kept the investigation open.

Does anyone have information about the night of November 7, 2013, or contacts who might help close this case?
