Found human poop in wall of home 😭

You guys - my husband and I just moved into a new house. It was only occupied for six months before we moved in. We just found out from a bunch of neighbors that the previous owner found a bag of human poop and pee in one of the walls behind some insulation when he went to finish the room (it was left unfinished).

I’m ready to put it back on the market. What would you do?? I guess they confronted the builder and he blamed it on squatters. The neighbors said there were never any squatters here.

Ughhh I feel sick. How disgusting. I wonder what else they did to the home. I have three kids too and feel concerned about raising them here now. I’m so grossed out and disturbed. 😭
