A city in Michigan is perplexed after a mysterious tar-like substance has rained down on their cars, porches and driveways this week, leaving residents bewildered as it covers cars, porches and driveways.
The black, oily substance first appeared on at least six driveways in Harrison Township, Michigan, on Sunday. The mystery substance was seen on resident’s roofs, cars and porches.
Michigan Department of Environmental Quality officials collected samples of the substance on Wednesday. The residents originally believed the substance could have come from the nearby Selfridge Air National Guard Base. The airbase released a statement saying it was not coming from their area.
The statement said the airbase has ‘been in communication with the Michigan Dept. of Environmental Quality, which was sending a representative to the area in question to review the material’. At this time, it could be at least a week before the city discovers what the substance is.
