MARENGO, Wis. (AP) — Authorities say two people died when a single-engine plane crashed into a home in northeastern Wisconsin.

The Ashland County Sheriff’s Office received numerous 911 calls about 2:40 p.m. Saturday with reports of the crash in the town of Marengo, located about 80 miles from Duluth, Minnesota. No one on the ground was hurt, authorities said.

The Sheriff’s Office said the victims are a 29-year-old man and a 21-year-old woman from Marengo. Investigators do not believe anyone else was in the plane.

A news release from the sheriff’s department offered “deepest condolences to the family of the victims” and said the office will “share further information with the public regarding this incident as it becomes available.”

The National Transportation Safety Board is investigating.
