"It's my fault, Mauri, wake up."

A heart ravaged by grief: " It's my fault, I told him to wait. Mauri, now wake up ." A soul torn by anguish: "It's my fault, I didn't notice anything, I have a brother his age." A heart ravaged by grief.

On State Road 130, shrouded in darkness broken only by the flashing lights of the ambulance, the tragedy of yet another life taken unfolds . Very young: the lifeless body of Maurizio Porcu, just 19 years old, lies on the ground, covered by a white sheet after nearly an hour of desperate attempts to resuscitate him by 118 emergency responders.

All around is pain, the screams of despair that follow an initial, eerie silence. And a sense of guilt that paralyzes those left behind. The girl who, running in her pajamas to her long-awaited friend, is devastated for not having been there sooner ; and a boy sitting on the asphalt with his hands in his hair, devastated for not having seen him in time.
