Loud bang heard while investigating the Monroe house – 04/07/2023

While investigating the Monroe house, we were in the basement performing the Delco experiment and caught this loud thump at 2:45 am that sounds like something being dropped on the floor upstairs. We were the only ones in the home since we arrived at 4:30 pm, The thump was so loud it caught Jayden off guard and I could hear it thru the headphones, we immediately went upstairs to see if we could find the source, but nothing was touched or had fallen !
