Carlo was Roberto Anzalone's graduate student and travelled on the expedition with Anzalone, Malcolm Quarrie and Major Ricardo Delnegro.

His diary (both in Italian - Page 1, Page 2, & Page 3, and translated into English Part 1 & Part 2), discovered in the Nepalese village of Kag, shows a great mental deterioration after reaching Drakmar. According to reports from Te he had returned alone from Drakmar, claiming his companions had been 'taken by ghosts' and was being nursed to health by the monks.

When the investigators reached the Monastery at Te they came under fire from Schippone, who wounded their guide before Captain George Withers put a bullet through his brain from long range. It was discovered that Schippone had killed the monks and had been living alone in the Monastery for many weeks.

At Drakmar the investigators discovered that Schippone had murdered Major Delnegro after the mental influence of Chaugnar Faughn sent him into insanity. He fled the scene before Quarrie or Anzalone could stop him.
