Fabian had told police he planned a romantic dinner with his girlfriend on October 11 but it ended abruptly after they allegedly fought about an ex girlfriend of his.
Police have also charged his friend Chris Estrada with helping him dispose of Verk's body.
Estrada has admitted he drove Fabian to a store on October 12 and let him use his card to buy plastic sheets, the type Verk's body was wrapped in when it was found.
Neighbours also told police that Fabian had played a movie loudly between 1am and 2am, and had then driven off alone at around 4am.
And one friend told police that he had said: "If I know a really big secret and two people know it, then the other has to be dead."
