Carver

 was a folding man.

He had joined a gang of folding men lead by a gangster named Nomad. Nomad got him addicted to a pain killing drug (TPG) made of gold. When Aaron Braithwaite began to question Nomad's methods, he was killed and stuffed in a washing machine. When Carver discovered this, he shot and killed Nomad but not before Nomad did the same to him.
