Do I have any legal ground to file a police report?

My girls went to a neighbor’s to celebrate New Year’s with friends. They were told to be home at midnight. They never came home, and the neighbor would not answer my phone calls or texts. It looked like their lights were off, so I thought they had fallen asleep, but had a weird feeling, and repeatedly called until 6 am. I didn't call the police because I thought I was friends with this person, and they are on probation and her boyfriend is on parole, and I didn't want to get them in trouble for living together. Well come to find out, the woman lied to my children and told them she talked to me and that I said they could stay, but I think she did this because of the events that unfolded at her house. Her boyfriend screamed at mine and her children to get out of the living room because my daughter accidently spilled his beer all over her pants. They told her she had to wear them until bedtime, so she was stuck in beer soaked pants for a bit. Then her kids thought it would be a great idea to prank 911. They went and told the mom what had happened, and speaking to my children as well as hers. My children are 8 and 10. She then proceeded to say the cops were coming to scare the kids. After they were terrified, she then told them to remember that feeling because that is how her and her boyfriend felt. She proceeded to tell my children not to say anything to me. She said if they didn't tell she wouldn't tell, and to imagine how much trouble they would be in. I feel that they were worried my kids would tell me, and out of fear because they’re on probation and parole. They held my kids overnight. I'm worried that nothing may come of this, and that there will be retaliation.
