Both NOAA and KSBW call out the man in the picture – who was not their man.

A woman walking along Point Pinos Beach in Pacific Grove reported witnessing a man and his daughter mutilating the carcass of a dead seal back in June to KSBW 8.
Several months later, NOAA got involved and announced a $20,000 reward for information leading to the arrest of the man wanted for doing this.
The incident occurred at 8:40 p.m. on July 27. NOAA says the sea lion was dead before being decapitated, and its cause of death was not determined.
“We are seeking information on the person who decapitated the animal and any other details surrounding the incident,” said NOAA.
