His employer stole his gold, and when Stark tried to sue him for theviery, he lost the case, because Hank "Misplaced" a certain piece of evidenced

In 2012 Stark broke out of prison, by beating two guards into a comer, and went on a rampage looking for revenge, as his kind was renound for taking grudges to there grave. He first attacked the Judge who procecuted him, murdering him in an unspeakable brutal method of forcing his gavel down his throat. Next he murdered the man who gave the Judge the verdict and then his defense attorney.

He began searching for Hank, to end his Vendetta, he attacked an elderly man and blew up his car near Hanks old residence, unaware Hank had moved. Still getting no where he broke into Nick's home, Nick tried to fight back, but Stark's supreme strength and durability proved to much, he began trying to beat the information out of Nick, before realising Nick was a Grimm. This caused him to turn more violent. At that moment Nick's girlfriend returned, panicking she tossed a pan full of boiling water over Stark, and in the agony Nick managed to reach his gun, after firing at Stark three times, Stark retreated. But put Nick in the hospital.

Meeting up with Monroe, Monroe explained that Seigbarste's were next to invulnerable and the worst of all Wesen. Nick however remembering what he read in one of his ancestors diaries, remembered that a previous Grimm had invented a weapon to combat them. A three barrel elephant gun, with bullets coated in a special poison would kill even Stark. As Nick was hospitalised Monroe had to get the gun.

Meanwhile, having finally driven him out, Stark met Hank, Hank tried to fight back, but Stark easily smashed him down, he lifted a giant slab, planning to crush Hank with it, but Monroe having collected the rifle, shot Stark in the back, the powerful gun proved to much even for the giant ogre, and he was killed instantly.
