On the night of July 25, 2015, a house party on Lavender Lane in Mechanicsville, Maryland, ended in the fatal shooting of 21-year-old Cody Michael Lacey. The shooting left one man dead and prompted an immediate search for a suspect.

Police identified 21-year-old Alan Michael Rangel as the primary suspect and issued a warrant. Rangel was located and arrested on July 27, 2015, in Jessup by the U.S. Marshals Service Task Force Fugitive Unit. Amanda Raye Hartmann, 24, was arrested with him and charged as an accessory after the fact to first-degree murder. Two other men, Wade Joshua Braithwaite and Demetrius Jose Burks-Jeffrey, were also arrested as accessories after the fact; a search of a Lexington Park residence where they were found produced a weapon.

In January 2016 a St. Mary’s County jury convicted Alan Michael Rangel of second-degree murder after a three-day trial, and on April 14, 2016, he received a 90-year prison sentence that reflected multiple charges. Braithwaite later pleaded guilty to possession of a firearm by a felon.

Did anyone at that 2015 party or living nearby notice anything unusual that night?
