MARENGO, Wis. (AP) — The brother and sister who died when their small plane crashed into a house in a tiny, northern Wisconsin town were known to the homeowners, who escaped injury. The single-engine plane went down Saturday afternoon in the Ashland County community of Marengo, home to about 400 residents located about 80 miles from Duluth, Minnesota. The sheriff’s office says 29-year-old Aaron Mika and his 21-year-old sister, Aleah Mika died at the scene. Martin Ollanketo says he and his wife were watching TV when they heard what sounded like a bomb. The plane crash destroyed their front porch. The homeowners knew the couple killed, recounting their graduation parties that they attended.
