It's not the first time it's happened unfortunately but this is one of the few times that there is video evidence of this type of assault/attempted murder.

A few years ago off the coast of Florida a diver was found dead initially it was suspected it was due to drowning due to inexperience but further investigation found that the diver had been intentionally killed and while the death hasn't been solved the area the diver was found was infamous for unscrupulous people illegally collecting coral and fish for resale

It's not an isolated case it's just not well reported or documented and it happens throughout the world in both fresh and saltwater. People are willing to commit murder for anything because its big money
