Three young men were found dead near Holmen, Wisconsin, in the early morning of July 23, 2021, when quarry workers arriving for their shift discovered their bodies at the entrance to the Milestone Quarry on County Road M. One of the victims was 24-year-old Peng Lor; the others were identified as 24-year-old Nemo Yang and 23-year-old Trevor J. Maloney.

Investigators determined the killings were targeted. A witness said the three men were forced to their knees and shot multiple times in an execution-style killing. Authorities alleged the motive stemmed from a dispute over about $600, with one of the accused believing he had been robbed. Two men, Nya Thao and Khamthaneth Rattanasack, were charged in the case. Court testimony described Rattanasack accusing the victims and handing a gun to Thao, who then carried out the shootings.

Khamthaneth Rattanasack pleaded guilty to one count of first-degree intentional homicide as a party to a crime and received a life sentence. Nya Thao was later found guilty by a La Crosse County jury on three counts of first-degree intentional homicide and one count of being a felon in possession of a firearm.

If anyone knew Peng Lor or has information about the events that led to that night, please come forward with what was seen or heard.
