A San Francisco, CA man was killed by exsanguination in Mexico when a grey shark bit his right thigh, bringing the total to four shark attacks on US citizens in as many days.
According to CNN, the victim suffered wounds “that reached from the hip to the knee, exposing the femur.” The victim was still alive when he was brought back to the beach. It took so long for the ambulance to reach the relatively isolated, undeveloped beach that a bystander took the victim to a local hospital in his car. The man died from loss of blood a few minutes after reaching the hospital.
The last shark attack in Mexico was in 2006. It was not fatal.
