A reward for information about the recent deaths of two slain dolphins along Florida’s Gulf Coast has increased from $20,000 to $54,000.

Reward offered for information after dolphins found stabbed, shot to death off Florida coast

Officials found one dolphin in the water off Naples killed by a bullet, stab wounds, or possibly both.

In the same week, along the Emerald Coast, Wildlife Refuge also found a dolphin with a bullet in its left side along Pensacola Beach.

The National Oceanic and Atmospheric Administration had offered a $20,000 reward last month. The federal agency announced Monday that it was combining that reward with another $34,000 pledged by animal rights groups.
