A tourist from the U.S. mainland who was visiting Puerto Rico for Bad Bunny’s residency was fatally shot early Sunday at La Perla, a popular seaside shantytown, police said.

The shooting happened in the predawn hours on Sunday in the popular seaside shantytown of La Perla near Old San Juan, Puerto Rico.

La Perla is located on the outskirts of a historic district popular with tourists known as Old San Juan. A couple hundred people live in the shantytown, which once served as Puerto Rico’s biggest distribution point for heroin and was known for its violence.
