Nun involved in Katy Perry lawsuit dies after collapsing in court
A nun involved in a lawsuit with pop star Katy Perry over the sale of a convent in Los Angeles died after collapsing during a court appearance.
Archbishop Jose H Gomez said Sister Catherine Rose Holzman died on Friday. She was 89.
"Sister Catherine Rose served the Church with dedication and love for many years, and today we remember her life with gratitude," Archbishop Gomez said in a statement on Friday.
Hours before her death, Sister Holzman spoke to KTTV, speaking out against a judge's ruling that cleared the way for the Archdiocese of Los Angeles to sell a convent in the Los Feliz neighbourhood to Ms Perry.
The singer sought to buy the 32,375 square metre property and its Roman-villa style buildings for $14.5 million (Dh53.3m).
The nuns had tried to sell the convent to a local restaurateur to turn it into a boutique hotel, but a judge ruled in 2016 that the sale was invalid.
