The psychiatrist for Adam Lanza, the man who gunned down 26 people at Connecticut’s Sandy Hook Elementary School in 2012, has admitted sexually assaulting an 18-year-old girl whom he was also treating, according to a report.

Paul Fox, 66, pleaded guilty to one count of second-degree sexual assault under a state statute that prevents psychotherapists from having sex with their patients, the Connecticut Post reported.

He faces 18 months in jail plus 10 years probation.

There was no indication that the psychiatrist had any abusive contact with Lanza, 20, who himself had an interest in sex with children — and may have believed he was “saving” the ones he murdered, according to documents first released in 2017.
