Nathan T. Ratigan, 24, was shot and killed outside a house party in the 300 block of West Marshall Street in Richmond just before 1 a.m. on October 7, 2012. He was taken to VCU Medical Center but died shortly after arrival. Reports describe him as a generous young man who loved music and traveled to festivals around the country.

Despite an active investigation, no arrests or publicly identified suspects have been reported and the murder remains unsolved. Authorities have repeatedly asked the public for information that could identify whoever was responsible.

If anyone was at that gathering or remembers seeing anything that night, can you share what you know with investigators?
