UPDATE: Channel 3 is learning more about the man who died while kayaking on Sunday from his girlfriend.

Twenty-seven-year-old Christopher Goodine died after his kayak tipped over and he fell in the water.

Goodine and his girlfriend, Ashleigh Renko, were swimming and kayaking, when Goodine drowned at Harrison Bay State Park.

A TWRA spokesperson said investigators don't know exactly how he drowned. The spokesperson said people at the marina nearby saw him struggling to swim.

Eric Crawford was one of about 20 people who jumped in to try and help.

"Heard commotion coming from across the inlet, and then we heard somebody yelling call 911,” Crawford recalled. “So a few of us jumped in the water to go see if we could help."

Goodine was about 20 yards from the shore and in about 10 feet of water.

He did not have on a life jacket, and there was not one on the kayak.

Goodine's girlfriend, Ashleigh Renko, is still trying to figure out how to deal with the loss.

Renko told Channel 3:  

"Chris was everything to me. We were always trying new things and he was so supportive. Everyone around him loved him. He lit up a room everywhere he went."

A spokesperson for TWRA said kayakers are not required to wear a life jacket. However, they do recommend wearing one anytime you are in open water.
