“The end of January 2017, Joe was being distant from me and turning me down for sex,” Angie says. “Because I suspected Joe was cheating, I put my phone downstairs in the garage to record him. I heard what I believe was a female voice talking about having a secret affair.”
 
Angie says since then, she has installed surveillance cameras in their home and a GPS tracker on his car, and follows him around the house.
