The Associated Press is reporting that a giant wave hit two tourists on a beach in Cabo San Lucas, dragging them out to sea and killing one of them.

A 65-year-old woman was killed by the freak wave, while a 70-year-old man is now in serious condition. The wave struck near the famous El Arco natural arch at the resort community, located at the southern tip of Mexico’s Baja Peninsula.

The AP report quotes state police as saying the man and woman were walking along the beach to their hotel when the incident occurred. The Navy was dispatched to recuse them, but the woman later died.

Officials have not released the names of either of the victims, though authorities told the AP that the woman was carrying a driver’s license from Wisconsin, while the man was carrying one from Nebraska.

Cabo San Lucas is a popular tourist destination for its beaches. Tourists and cruise ships come to the beach resorts there to scuba dive, watch the abundant marine life, and surf the waves.
