Manuela Calderon oversaw security operations at Grey Ridge Mine.
After being hit by sonic cannons, Carnage and a team of F.B.I. agents fell through a fracture into a played-out section of the mine.
A Chthonic temple was hidden in the depths of the mine.
It was accidentally discovered while the Grey Ridge Investments workers were pursuing a coal seam.
The temple was eventually destroyed when the mine collapsed over it.
