Catholics from across Argentina have flocked to churches to pray for the recovery of native son Pope Francis, the first Latin American pope in history.

A lawyer for Luigi Mangione, the man accused of fatally gunning down U.S. health insurance executive Brian Thompson in December, told a judge Friday that her client was illegally searched during his arrest and she would seek to exclude that evidence from his trial on state murder and terrorism charges.

The Pope was admitted to Gemelli Hospital on Feb. 14 after struggling for several days with bronchitis. Over the weekend the Vatican said the Holy Father had suffered a respiratory crisis and required a blood transfusion, with the Holy See on Sunday evening stating that Francis’ condition was “critical.”
