Judge rules defrocked ex-cardinal McCarrick unfit for sex abuse trial due to dementia

McCarrick was the highest-ranking Catholic official in the US charged with sex abuse.
He was accused of assaulting a teenage boy in the 1970s.
A judge dismissed the charges after psychologists deemed him incompetent to stand trial due to dementia.
McCarrick was defrocked by the Vatican in 2019 after being found guilty of abusing minors and adults.
He still faces a criminal sexual assault charge in Wisconsin brought by the same accuser.
