(WFIE) Loud, mysterious booms heard overnight have Indiana residents scratching their heads.
The Vanderburgh Sheriff's office has investigated the noises, but found nothing.
"The sound was like a war bomb," Stacy Lowery said.
Lowery, who lives in Newburgh, had just put her kids to bed and was sitting on the couch when she heard it Tuesday night.
"A huge explosion, like definitely knew it wasn't a firecracker going off. I've never heard anything like it, very disturbing," Lowery said.
Lowery wasn't the only one.
Evansville Dispatch got several calls between 9:30 and 11 Monday night reporting an explosion.
"We obviously dispatched cars. I believe the EFD dispatched crews, the EPD. At the end of the day, we're not able to find anything," Sheriff Eric Williams said.
Crews scoured the area, but didn't find anything.
"It had to be something a little bit different than the typical explosion," Sheriff Williams said.
But what?
It wasn't an earthquake. The USGS doesn't have reports of any activity in our area.
The Air Force says it wasn't performing any military drills, either.
Interestingly, there have been reports of unexplained booms from Arizona to Rhode Island. No one has been able to explain them.
