I contacted Grey Private Investigators because I was worried for my Daughters safety. I thought her Father was hurting her but the team at Grey Investigators got photographs of his new girlfriend being abusive. I’d like to thank all the team. My Daughter is now safe and the courts have given me full custody with the evidence I had from the investigation.
