David MacDonald Carroll (born 1 April 1952), better known as "Wolf", is a Canadian outlaw biker and reputed gangster who was a member of the elite Nomad chapter of the Hells Angels Motorcycle Club in Quebec.

[5][6] By 1971 it had gained a large following and had formed a relationship with the Popeye Moto Club, a notorious Quebec-based biker gang which, in 1977, would eventually become the very first Canadian chapter of the Hells Angels.

[9][10][11] The Thirteenth Tribe won the trust of the Hells Angels by providing in the fall of 1984 bodyguards for Walter "Nurget" Stadnick as he was recovering in a Hamilton hospital from the traffic incident that disfigured his face.

[13] The 6'3 policeman and former football player John Gordon Harris warned Carroll that if he did not cease his unruly behavior, he would have him and the rest of the 13th Tribe arrested.

[14][1] A report from the Royal Canadian Mounted Police (RCMP) described the "patch over" of the Thirteenth Tribe as a move "to consolidate control of drug trafficking on Canada's East Coast".

[18] One prostitute who felt that Carroll was the greediest pimp in Halifax complained to the police that he had given her a vicious beating because she refused to hand over 40% of her earnings to him.

[22] On 7 April 1988, Carroll was again charged with first-degree murder in the connection with the death of a young man in Dartmouth said to be in a drug debt to the Hells Angels, a trial that again ended in his acquittal.

[26] Carroll wore the Hells Angels' "Filthy Few" special patch consisting of the SS lightning bolt runes.

[27] In the outlaw biker subculture, wearing a special patch with the SS lightning bolt runes is believed by the police to indicate that the wearer has committed a murder.

[32] The Demons Keepers were founded in January 1994 and collapsed by April 1994, a failure that Kane blamed on Carroll, whom he stated was too drunk to provide the necessary support he needed.

[33] Carroll was described by journalists such as Julian Sher, William Marsden and Peter Edwards as an arrogant, ill-tempered bully with an intense contempt for anyone who was not a Hells Angel.

[37] In his reports, Kane described Carroll as personally collecting intelligence on the Rock Machine, which was unusual for a "full patch" Hells Angel.

[33] Kane found himself in the middle of a power struggle between Carroll and another Hells Angel, an American living in Montreal named Scott Steinert.

[39] The journalists Julien Sher and William Marsden wrote the feud between Carroll and Steinert was like "the twisting schemes of ambitious and sometimes psychotic medieval princes".

[46] Besides for Carroll, the other members of the Nomad chapter were Stadnick, Boucher, Steinert, Donald "Pup" Stockford, Gilles "Trooper" Mathieu, Richard "Bert" Mayrand, Luc Bordeleau, Pierre Laurin, Louis "Mélou" Roy, Richard "Rick" Vallée, André Chouinard, Michel Rose, Denis "Pas Fiable" Houle, Normand Robitaille, Normand "Biff" Hamel, and René "Balloune" Charlebois.

[47] Steinert was described as a businessman who was concerned with only making money who went to bed early to start work promptly in the morning while Carroll was described as a man who liked to stay up as he enjoyed hosting parties.

[55] The sergeant-at-arms, Danny Fizsimmons, was a bad-tempered thuggish man who once attacked a CBC cameraman at a biker event and went to prison for assault.

[55] The only member of the 13th Tribe left in the Halifax chapter by the 1990s besides for Carroll and McCrea was Michael "Speedy" Christiansen, who spent 10 years in prison for raping a 16 year-old girl in 1971.

[44] During a party in Halifax hosted by Carroll on 12 May 1996, Magnussen impulsively killed David Boyoko, a member of Winnipeg's los Bravos gang who were considering joining the Hells Angels.

[59] In February 1997, Carroll came into dispute with Robert MacFarlane, a prominent Halifax businessman who owned cellphone and security companies who was known to be linked to the Hells Angels.

[67] Their bodies were later found floating in the St. Lawrence River with their heads bashed into bloody pulps after being repeatedly hit with baseball bats and hammers.

[70] Carroll became involved in a feud with a former Hells Angel, Randy Mersereau, who had broken away from the Halifax chapter to found his own group.

[55] Carroll also had a tense relationship with the Marriott family that dominated the drug trade in Spryfield, but who were willing to work with the Hells Angels.

[74] Facing charges of first-degree murder, Billy Marriott was found hanged in his cell in the Halifax Correctional Centre on 7 August 2000.

[79] Kane reported that Carroll wanted him to kill Gennaro Raso, the president of the Loners Motorcycle Club, in order to improve relations so that the Para-Dice Riders would join the Hells Angels.

[81] According to Kane, Carroll had told him that was $500, 000 in debt to la table faction of the Hells Angels and he was desperately looking for a way to make more money.

[83] Kane further mentioned that Carroll was deeply unhappy with the way that la table dominated the Hells Angels in Quebec and he was thinking about returning to Nova Scotia.

[83] Carroll used as an example that Boucher had promoted René Charebois up to being a "full patch" Nomad without consulting him in clear violation of the chapter's rules.

[3] Later on the evening of the same day, Kane reported that he attended a meeting in the Halifax clubhouse and that: "Mike [McCrea] and Wolf talked about having Kirk killed.

[87] On the morning of 28 March 2001, an extradition request was filed with the Mexican government for Carroll together with two Hells Angels in Mexico, Yves Dubé and André Chouinard.
