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.
