On May 23, 2000, David Jackson rescued a fisherman from his submerged vehicle, in Jewel Lake, British Columbia. The fisherman was loading his boat onto his truck when the vehicle suddenly rolled backwards into the lake. He jumped inside to try to stop it but the truck floated away. He was trapped inside the vehicle that quickly filled with water and sank, some seven metres from shore. Alerted by screams, Mr. Jackson entered the cold, murky water and dived down to the vehicle, stuck in the silt-covered bottom, some five metres below the surface. Although forced to come up for air several times, he persevered in his efforts to pry open the passenger's door, inches at a time. Squeezing his upper body through the doorframe, he then groped inside the cab until he felt the man's unconscious body. Despite failing strength, Mr. Jackson grabbed hold of the victim's shirt, managed to dislodge the man's foot, which was pinned between the door and the frame, and pulled him out. Once on shore, Mr. Jackson revived the victim with the assistance of others.
