PITTSBURGH (AP) — Two children who died saving the lives of even younger children are among 21 people being honored with Carnegie medals for heroism.

The Carnegie Hero Fund Commission, based in Pittsburgh, announced the winners Tuesday.

Natalie Renee Martin, 11, of Sheboygan Falls, Wisconsin, led her 9-year-old sister, Jenna, to safety when their house burned on Jan. 26. Natalie went back into the house attempting to rescue two other siblings, 10-year-old Benjamin Martin and 7-year-old Carter Maki, but all three were trapped and died later of complications from smoke inhalation.

Kiera Vera Larsen, 10, was killed Feb. 22 when she pushed 2-year-old Emmah Gusich out of the way when a parked vehicle began rolling down a sloped driveway toward the toddler in El Cajon, California. Kiera was struck and killed by the vehicle.

The commission is named for the late steel magnate and philanthropist Andrew Carnegie, who was inspired by stories of heroism during a coal mine disaster that killed 181 people, including a miner and an engineer who died trying to rescue others.

The commission investigates stories of heroism and awards medals and cash several times a year. It has given away $38.7 million to 9,914 awardees or their families since 1904.
