WEST SALEM, Wis. (WKBT) -

24-year-old Jeffrey Ozanne of the La Crosse area attempted to swim across the entire English Channel Sunday.

Ozanne wanted to do it to raise awareness for his sister's rare disease of Complex Regional Pain Syndrome. It causes her to be in pain 24-7.

Unfortunately, according to the Facebook page tracking his progress, Jeffrey suffered a cramp while swimming the channel and became too cold. It forced him to stop short of his goal.

Even though he didn't make it, his sister Emily says she's proud he gave it all he could.
