After a month at UCLA Medical Center following her June 5 suicide attempt
, Paris Jackson
left the hospital on Tuesday and headed to an undisclosed residential treatment center
, a source confirms to PEOPLE.
The facility was selected by the 15-year-old's grandmother Katherine
and her biological mother Debbie Rowe
on the advice of Paris's UCLA doctors
As for why the need for such continued, seemingly intensive, treatment, "The feeling is that Paris is still a danger to herself," explained the source. "Both Katherine and Debbie want her to get the help that she needs."
