Colin-Michel Demgé, 33, known as DJ Troutski in Milwaukee’s electronic music scene, was fatally shot outside his rear cottage in the Riverwest neighborhood shortly before 1:00 a.m. on November 12, 2016. Neighbors reported hearing multiple gunshots and calls for help; several residents tried to assist but Demgé died at the scene. Police opened a homicide investigation but had not announced any arrests or identified a suspect in the days after the killing, and no motive was disclosed.

Demgé was a resident DJ at Studio 200 and ran weekly Dig Deeper events that promoted underground electronic styles and emerging performers. Friends and fellow musicians remembered him as generous, adventurous in his tastes, and a mentor who supported new artists. Fundraisers and memorial concerts were held to help his widow, Liz Getschow, and to celebrate his work; family and friends continued to press for answers about who killed him.

Did anyone in Riverwest or Milwaukee’s music community witness the shooting or have information that could help explain what happened?
