24-year-old San Francisco resident Adrian Ruiz was killed by a tiger shark while surfing off the coast of Mexico yesterday, making this the second shark-related death in the past week. According to AP, "Ruiz bled to death on Monday after a tiger shark bit his right thigh, leaving a 15-inch wound, the Guerrero state Public Safety Department said in a statement."

Similar to the shark attack that took the life of triathlete Dave Martin, Ruiz was pulled ashore, but then alter died due to serious blood loss at a nearby hospital.

The fatal shark attack occurred at Troncones on Mexico's coastline, "about 325 yards from shore." The shark that attacked Ruiz is reported to weigh as much as 660 pounds.
