Police and firefighters in Colonial Heights were called out to three different parts of the city Sunday for reports of mysterious sounds. Some call them booms while others referred to them as explosions. Some said the noises were so intense that they rattled their homes. "It's a loud, loud boom," Clint Lanier, who lives in Chesterfield County, told CBS 6 senior reporter Wayne Covil. "It' ain't no shotgun and it ain't no kind of gun. It's like an explosion." Sgt. Rob Ruxer with Colonial Heights police said dispatchers received at least three calls just before 5:30 p.m. Sunday from citizens in separate areas of the city about a loud noise. "There was a large boom. I thought it was thunder," Kelsey Barnes of Colonial Heights said. "It kind of shook the house a little bit, but I have no idea what it was." Officials have not been able to tie the booms to one specific area, but they have been reported for the past several weeks. "Well it definitely grabs your attention and you think, 'why on earth is that going on at this time?" said Carolyn Thompson of Colonial Heights. Those who have heard the boom said it does not happen again for several days - and the sound varies. John Thompson, who heard the boom In Colonial Heights, said it sounded like a Sonic Boom from a jet. He said he did not think it was fireworks because there was only one boom. Colonial Heights residents Susan Crane, who also lives in, said she was watching TV when she heard the boom Sunday. "I've heard it numerous times," Crane said. "I usually get up and look out my door, like I'm going to see something, but there's nothing to see." CBS 6 News checked area surveillance cameras across the city and could not find sign of the boom. With every recurrence, there has been no revelation about what or who is behind them. Colonial Heights Fire Chief A.G. Moore said his department does not have any additional leads about what is actually the noise folks are hearing from Chester to southern Chesterfield and Colonial Heights. On social media there is a lot of speculation about what could be causing the booms.
