Joel M. Dammann, 27, was shot and later died on September 3, 2014, after a prearranged meeting to buy heroin at a hotel on Layton Avenue in Greenfield, Wisconsin. Dammann had been accompanied by a passenger when he met 20-year-old Daven Dodson of Milwaukee to complete the purchase. After the exchange, Dodson followed Dammann’s car in his own vehicle and, according to the passenger, caught up with them while shouting that he had received only $80.

The pursuit continued to the area of 27th Street and Cold Spring Road, where Dodson opened fire at Dammann’s vehicle. Dammann’s car crashed; he was taken to a hospital and died of a gunshot wound to the back of his head. The passenger was not injured. Investigators identified Dodson as the primary suspect, and the vehicle description given by the passenger helped lead to his arrest. Dodson later pleaded guilty to first-degree reckless homicide and was sentenced.

If anyone knew Joel, witnessed the shooting or the vehicles involved that day, please come forward with information.
