One person aboard a single-engine ultralight plane died Thursday evening when the aircraft crashed into a vacant house in Marathon, police said.

“No one on the ground was injured,” said Adam Linahrdt, spokesman for the Monroe County Sheriff’s Office. “How many people aboard the aircraft is under investigation.”

Police did not immediately release the person’s name, age or address. They are trying to notify the family first.

The plane crashed on 76th Street at about 5:10 p.m. and the impact caused a small fire that was put out within minutes, according to the sheriff’s office.

A parachute was found near the crash site.

The primary investigators are the Florida Highway Patrol and the National Transportation Safety Board.
