Should I check up on him and his daughter?

I baby sat for this dad and his daughters. He's a single dad and mom isn't in the picture. I accidentally walked in on his 8 year old masturbating. That was fine. Kids touch themself... Then she started doing other stuff... Like she would make her barbie pretend lick her down there and say some sexual stuff. I followed advice in here and told her dad. He made sure all the parental locks were still on and when he asked her where she learned that from she said it was a secret. Then he did take her to a psychologist and ig now they know where it came from and there's a police investigation. He hasn't asked me to babysit because of what's going on but he did let me come over to see her. Now idk who did it to her, but all I can say is it started around when his dad got a new girlfriend and the day after they saw the psychologist he's single on Facebook again and ALL her pictures are deleted.... So do with that information what you will. I know they're both going through a lot rn.... Should I reach out and ask how they're doing?
