Michael Agerter, 31, was fatally shot in the garage of his Maricopa, Arizona, home on December 16, 2016. He had just returned from a court-ordered paternity test and was on the phone with his sister when she heard him exclaim and heard three gunshots. Neighbors reported hearing the shots and saw a white van speed away. Police found Agerter in his running car with gunshot wounds to the head, neck, and upper body; he was pronounced dead at the scene.

Investigators focused on Agerter’s ex-girlfriend, Kathryn Sinkevitch. The two had met online in 2013 and had a history that included domestic violence and an order of protection. At the time of the killing they were engaged in a contentious custody dispute over their infant son; Agerter had been seeking to establish paternity and Sinkevitch reportedly opposed that. Surveillance from the house showed a hooded figure exit a white minivan, enter the garage, and return to the van within about 11 seconds; the van was later linked to a coworker of Sinkevitch. Workplace video placed Sinkevitch away from work long enough to account for the time of the shooting, and her phone records showed it was off the network around that time.

Does anyone have information about the white van, the figure seen on surveillance, or other details from that evening?
