An Indiana Conservation Officer saved a mans life after he was thrown from his boat on Mississinewa Lake Thursday in central Indiana.

Officer Hunter Law was patrolling the lake around 10:25 a.m. when he heard a boat engine rev up and then die according to a press release for Indiana DNR Law Enforcement.

Officer Law drove to the boat, but no one was on board. He later found Robert Boyd, a 76-year-old from Kokomo, just underneath the surface of the water.

Law pulled his body from the water and took him to shore where medics took him to the hospital.

Boyd was not wearing a life jacket, but he did have a safety lanyard attached to the engine cut-off switch, which is why the engine turned off when he was thrown.
