What Evidence that is sought through a police investigation of child abuse?

I believe you are asking what the police are looking for in a child abuse investigation? They are looking for signs and symptoms of child abuse. They will gather as much information as possible and the reason is two-fold- first is there a need to remove the children and second they are gathering information in case the incidents are severe enough to warrant criminal charges. If you are the alleged abuser you can talk to them without legal representation however I would recommend against that. Even a simple field interview (say done at your kitchen table around several cups of coffee) can be used against you prior to them reading you your rights. Additionally, IF you ARE abusing your children you need help. Let them help you and take them up on their offers of intensive services. There is NO excuse for child abuse.
