Southwestern Indiana authorities are trying to determine the source of mysterious late-night booms that are giving area residents a rude awakening.
Twenty-four-year-old Caleb Donahoo says he's heard the booms each night this week at his Evansville-area home. He says the first one, on Monday, was so loud it shook his home and rattled its windows.
Evansville-Vanderburgh County Emergency Management Agency director Sherman Greer tells the Evansville Courier & Press that so far, local authorities are at a loss to explain the loud noises.
The booms have fueled rampant speculation on social media, with theories ranging from a blown power transformer to a meth explosion or a sonic boom from some sort of aircraft. Others have speculated the noises could be mine blasts at a nearby coal mine.
