The report further suggests the 16-year-old told the court-appointed therapist about the abuse, where he admitted he experienced all the allegations that has been made.
The certified traumatologist and counselor concluded Kate's son was suffering from PTSD and trauma.

Currently, Jon Gosselin has the full custody of his son, Collin. But previously, Collin revealed on his Instagram post that he had beaten him.
Collin, on his now-deleted post, wrote,
"He punched me in the face and gave me a swollen nose, and I started bleeding. He then continued to kick me in the ribs after I was on the floor."
Following the report, Kate said,
"Until I receive the letter from CYS about whether they've deemed the allegations founded or not, it's ongoing. My contact at CYS has not told me otherwise. If this doesn't qualify as assault, I don't know what does."
She further added,
"No charges or citations were filed as a result of this incident. We are not investigating at this point."
To which Jon Gosselin said,
"I really didn't want to have to come out and talk about this for Collin's sake, but when Kate is in the media attacking me, calling me a child abuser, I have to defend myself. I love my son, and I would never hurt him."
