MINNEAPOLIS (WCCO) — Authorities are asking for the public’s help to find a vehicle that was involved in a hit-and-run crash Saturday night that killed two pedestrians in western Wisconsin.

Authorities say they’re looking for a black pickup truck — possibly a Ford, that could have front-end damage and certainly would have damage underneath the vehicle. At a press conference on Sunday afternoon, police said there could be a blue barrel in the back of the pickup, with amber-colored lights on top of the cab.

The Polk County Sheriff’s Office received a report of the incident at about 6:30 p.m. Saturday. Authorities said two men were hit by a vehicle that was traveling southbound on County Highway E in northeastern Polk County.

Officials say the two men were involved in some kind of altercation on the road — either verbal or physical — when a pick-up truck came down the road and hit both of them.

Witnesses told authorities after the truck hit the men, two white men inside the truck got out of the vehicle, had some sort of exchange, then got back into the truck and drove away.
