Description:
Joel Bacad was killed by an unknown shark while fishing with his 17 year old son. They were in waters "about three hours away" from the shore.
Joel dived into the water to examine their fishing net. He was attacked, likely due to the presence of bloodied fish. The shark gnawed at his back and right arm.
His son brought him to shore but he was dead by the time he arrived.
The attack occurred around 10 or 11 am.
