HUDSON, Wis. — Police are investigating a shooting that left three people wounded outside a liquor store in western Wisconsin.

Police Chief Marty Jensen said it happened before 9:30 a.m. Sunday in a parking lot at Spirit Seller Liquors in downtown Hudson. He said the victims and suspects were in cars with Minnesota license plates, and may have driven across the border to Hudson to buy alcohol because Minnesota liquor stores are closed Sundays.

Two men and one woman were taken to Regions Hospital in St. Paul. Their conditions were not available. Two male suspects were arrested at a hotel in Bloomington.

Liquor store owner John Kromer said it’s the first incident he’s had in 36 years there. He said the parking lot isn’t a place where people usually linger.
