I was searching YouTube looking for people using the Spirit Talker app and found this video. I was amazed by the responses this guy got while sitting in his car!! fast forward to 25 minutes and have a watch!
The video description reads:
For almost 30 years, nobody has been convicted of the four gruesome murders that occurred at the end of Cahaba Lane in Knoxville, TN. There has been a suspect who even admitted to the evil deeds, but there was never enough evidence to fully convict him. When I went out there to ghost hunt and talk to the spirits, I may have contacted someone who stated the real name of the killer… watch more to find out what they said.
