What is the full name of the person who obtained the soil with the biological agent? Answer the above question based on the context below: In the 2040s, a Martian research base, Tantalus Base outpost, is created. The eight person crew, who have been stationed there for six months, are only nineteen hours from the completion of their research mission. The spacecraft Aurora is inbound from Earth and will collect the team by lander. Mars scientist Marko Petrovic has found samples that may point to life on the planet. Without revealing his discovery, he devises a ruse for a last sojourn on the surface. Crewmate Richard Harrington drives Petrovic in a solar powered rover to the spot where he had found the sample. After he obtains soil with the biological agent present, a fissure swallows Petrovic. Captain Charles Brunel and crewmate Lauren Dalby plan to explore the pit to retrieve Petrovic's body. Dalby remains at the pit but disappears before the team can return with equipment. Brunel authorizes Vincent Campbell to explore the pit and he finds a fungus-like life that grows in the fissure. Dalby and Petrovic reappear at the main outpost, but the Martian bacteria has mutated them into fast, aggressive, zombie-like creatures with blackened skin and no trace of their original personalities. Harrington dies from a power drill attack by one of the zombies and later revives as one himself. The remaining crew hold off the zombies while Brunel and Campbell return. Brunel is also fatally injured and reanimates, which provides the crew with new insight into the symptoms: thirst, memory loss and aggression.

Marko Petrovic
