 Texas Parks and Wildlife says two people were hospitalized after shark attacks at South Padre Island on July 4th. Two others encountered the shark but were not seriously hurt. I started swimming towards them and then he jumped up out of the water saying, shark, shark, shark. Rainer Cardenas tells KRGV his son-in-law was the first victim and received a severe bite as they swam near Blackbeard's restaurant. Adrenaline kicked in and I went right after him. Brian McDaniel of New Brunsville says he saw the response to the first attack.
