Ninety miles north of Chiclayo, where Pope Leo XIV served for more than 20 years, a group of students from Bishop O'Connell found themselves unexpectedly responding to tragedy.

While on a mission trip led by Commissioned by Christ, the students helped rebuild the home of a local family that was destroyed by a fie. The fire broke out the night of July 8, leaving the family homeless.

When the students learned about the tragedy the following morning, they were heartbroken about the news but within hours were eager to step up and help.
