"Who Killed the Squirrels?" is an installation created exclusively for the 10 Sentidos Living Arts Festival in Valencia in 2019. The work was complemented by a live performance at the San Cristóbal de los Reyes library, a site that served as a Francoist prison until 1966.

The piece consists of ten panels. The front side is treated with a decollage technique, combining paint, screen printing, woodcut, other printmaking methods, and photography on wood.

During the live performance, audience members were invited to deposit anonymous testimonies of a personal, harsh, and violent nature into a box. Throughout the event, the backs of the ten panels were progressively filled by inscribing these publicly-submitted texts, confessions that people would typically be ashamed to voice openly. The reverse side of the panels employs the sgraffito technique, a process that simulates violent gestures. Using surgical tools to scratch the texts into the boards echoes the raw and visceral nature of the "beastly" confessions provided anonymously by spectators.
