Mech 354 was a scout specifically tasked by colonists of Gei Hinnom to investigate an unknown compound in the deep forests. Dr. Carol, now having raised the inhabitants alertness of geth on Gei Hinnom, simply hacked the mech and detained it inside the compound for his use. After that, colonists hired mercs to infiltrate the compound and investigate. They managed to deactivate the compounds barrier and enter. Only to be killed, one by one until the leader was the only one alive. And then killed by being placed into a saw machine.
