PITTSBURGH (AP) - A Nebraska girl who died of brain cancer Tuesday at age 3 is posthumously helping two Pennsylvania children.

Olivia Swedberg's mother saw 2-year-old Lucas Goeller's story on Facebook and messaged his mother in Pittsburgh telling her she wanted to give him Olivia's liver.

Goeller received the organ during a transplant surgery that began Wednesday night and ended Thursday morning.

Though their blood types did not match, doctors proceeded with the transplant.

Dr. George Mazariegos, chief of pediatric transplantation at the Lawrenceville hospital, tells the Tribune-Review that Goeller would have died within weeks without the new liver.

Angelo Giorno, of Hershey, received Olivia's intestine and spleen. The 4-year-old suffers from a condition known as short gut syndrome. He was born with his intestines outside his body.
