"I just looked down and saw a big, old fish," said Herrera.
The 3 1/2 foot Leopard shark was already dead.
"It was upside down, floating, so I just crawled in right there and pulled it out by its tail," said Herrera.
Once the shark was out on display, dozens of intrigued neighbors, like Brett Morris, gathered to see the odd sight.
"I noticed there was a shark on the sidewalk so I just had to jump out and check it out. It was pretty amazing," said Morris, who lives near the canal.
Clovis Police Animal Services officers picked up the dead shark and will dispose of it. No one may ever know if the shark was dead or alive when someone dumped it and police are not looking into the case.
"There's no evidence. It's not like you're going to get fingerprints from the fish," said Janet Stoll-Lee, spokesperson for the Clovis Police Department.
Leopard sharks are not a danger to humans and it's not illegal to have one as a pet. Source
