PITTSBURGH (AP) — A 12-year-old Maryland boy who died trying to rescue his younger brother from an icy pond is one of 22 people awarded Carnegie medals for heroism.

Aaron Robinson, of Cambridge, Md., fell through ice and drowned attempting to rescue his 8-year-old brother, Jairus, on Feb. 11, 2007. Jairus Robinson also died.

Three other people honored Wednesday by the Carnegie Hero Fund Commission died trying to rescue people. They are 27-year-old R. Jason Altman, of Andrews, S.C.; 27-year-old Randall Scott Brewer, of Lancaster, N.H.; and 41-year-old Paul Cossalter of Wrenshall, Minn.

Pittsburgh steel baron Andrew Carnegie started the fund in 1904 after hearing rescue stories from a mine disaster that killed 181 people. Since then, $31.5 million has been awarded to 9,284 people. Medalists, or their heirs, receive $6,000.
