Shortly after 1 a.m. on June 11, 2020, shots were fired near Hill and Court Streets in Sparta, Wisconsin. Officers found 61-year-old Anthony Koopman gravely wounded; he was taken to a La Crosse hospital and pronounced dead. Police said the shooting stemmed from a planned drug transaction that drew three people from Milwaukee to Koopman’s home and that the meeting, which began in a car outside the residence, devolved into an attempted robbery. According to later court filings, Koopman tried to flee and was shot during the altercation.

Within weeks investigators announced arrests tied to the trip from Milwaukee and the attempted robbery. Damara Skenandore-Medina, Michael Hartmann, and Eric A. Borges were all arrested in connection with the incident; Hartmann was later tried and convicted. The case centers on the drug deal that turned violent and the sequence of events that led to Koopman’s death.

Did anyone in the Sparta or Milwaukee area see activity around Hill and Court Streets on the night of June 11, 2020, or have information about the meeting that brought these visitors to Koopman’s home?
