We got called to this home when the parents told us there son was hearing voices & seeing figures. When we arrived we notice the homes were really close to each other. During our investigation we did not notice anything out of the ordinary. We did not find anything upon review & I let the client know. They called a few weeks later asking us to come back that there son said it was getting worse. This time only 1 of the investigators went and stayed let with the son. He noticed right away people talking outside and asked the son if that was what he heard. The son said yes. When he noticed the son was also deeply into video games we concluded the son was so into the video games he did not notice it was his neighbors.
