Three Italian brothers suffered heart attacks on the same day, killing two of them.

The third was already in the hospital at the time, visiting his elderly mother, and was immediately treated by medics, the Corriere della Sera reported Tuesday.

Guido Garofalo, 45, was the first to succumb while on a family picnic Sunday on the steep slopes of Sicily's Mount Etna volcano. His brother Alberto, 53, was overcome with grief on seeing him drop dead and suffered a cardiac arrest shortly afterward. He died despite the efforts of first responders sent to the scene.

The two victims' older brother Salvatore, 57, remains in stable condition after being treated for a blocked artery at the Garabaldi hospital in Catania, eastern Sicily.

A sister, who lives in Rome, has not been informed of the tragic deaths yet because she suffers from the same congenital heart disease, the paper said.
