Madrona Brown, 49, and her husband Larry Brown, 45, were found shot to death in the parking lot of an IHOP on the Evangeline Thruway in Lafayette, Louisiana, on the night of September 29, 2017. Officers discovered the couple after 9 p.m.; both died at the scene of apparent gunshot wounds. Madrona was from New Orleans; Larry lived in Lafayette.

The killings occurred in a public area and prompted an intensive investigation by the Lafayette Police Department asking the public for help piecing together what happened. A suspect, John Christopher McGraw of New Orleans, was later arrested in Marrero by the U.S. Marshals Service Violent Offender Task Force and charged with two counts of first-degree murder in connection with the deaths.

Does anyone have information about the couple’s movements that evening or who might have been in the IHOP parking lot that night?
