Firefighter donating part of his liver to sick little girl

BETHLEHEM, Pa. (WPVI) -- A Bethlehem firefighter is coming to the rescue of a little girl in need of a liver transplant.

Three-year-old Kennedy Stevenson has a rare genetic disorder that prevents her from producing protein.

Her mother posted a plea on Facebook looking for an organ donor who might help her daughter.

Mom's high school classmate Michael Thompson, who is a firefighter, volunteered to get tested.

It turns out... he was a match!

"If somebody calls 911, we're there to help if they need us - it's part of our job. Me doing this is something I thought would be nice to do and as of right now everything is working out," Thompson said.

He is donating a part of his liver.

The surgery is scheduled for later this month in Pittsburgh.
