After the coup, Pinochet's soldiers rounded up Chileans who were believed to be involved with leftist groups, including Allende's Popular Unity party. On the morning of 12 September 1973, Jara was taken prisoner, along with thousands of others, and imprisoned inside Chile Stadium. The guards there tortured him, smashing his hands and fingers, and then mocked him by asking him to play the guitar. Jara instead sung the Chilean protest song Venceremos. Soon after, he was killed with a gunshot to the head, and his body was riddled with more than 40 bullets.
