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. He disappeared in March 2001 after being indicted on 13 counts of first-degree murder.

Early career Carroll was born and grew up in Dartmouth, Nova Scotia. He became the leader of a Halifax biker gang known as the Thirteenth Tribe Motorcycle Club, which had been founded in 1968. The 13th Tribe Motorcycle Club had reigned as the dominant outlaw motorcycle gang in the province of Nova Scotia as early as the 1970s and its members had an outwardly defiant and hostile attitude towards police authority. 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. The Halifax underworld is very closely linked to the Montreal underworld and David Carroll soon had an alliance with the Hells Angels of Montreal. Like many other biker gangs around the world, Carroll and the rest of the 13th Tribe MC had a strong admiration for the Hells Angels MC and sought to emulate its organizational structure in their own club.

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. A nurse recalled: "It was crazy; most of the day there were these big, burly bikers outside his room. And the rest of the time it was these big, burly cops – it was like he was a rock star or something. You could tell these bikers were small-town boys; they weren't used to the cops like what we had here in Hamilton. They used to taunt and tease the bikers all the time – trying to start a fight, eh?". The 6′3″ (190 cm) policeman and former football player John Gordon Harris warned Carroll that if he did not cease his unruly behaviour, he would have him and the rest of the 13th Tribe arrested. On 5 December 1984, the Thirteenth Tribe became the first Hells Angels chapter in Atlantic Canada with Carroll as chapter president. This occurred on the very same day that the Gitans Moto Club of Sherbrooke had also been absorbed by the Hells Angels. 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".

Hells Angels The Hells Angels hitman Yves "Apache" Trudeau was told by the West End Gang boss Allan "The Weasel" Ross that he should collect the money owed to him for four murders that Ross had hired him to commit from the Hells Angels chapters in Halifax and Sorel, which were in debt to Ross. Ross promised Trudeau that he was willing to forgive those debts if the two chapters paid the money owed to him to Trudeau instead. Carroll, as the president of the Angels' Halifax chapter, paid Trudeau $98,000. Carroll later learned that the Laval chapter was actually entitled to one-quarter of the money, and that Trudeau had used the extra money to support his cocaine addiction. Carroll met with Réjean "Zig Zag" Lessard of the Angels' Montreal South chapter to discuss the matter, and it was decided to take action against the Angels Montreal North chapter, to which Trudeau belonged. Carroll was involved in the plans for the Lennoxville massacre, working with Lessard to discuss plans to remove the Montreal North chapter, whom Carroll and Lessard had decided were a liability for the Hells Angels. In March 1985, Carroll went to Quebec to assist Lessard against the Laval chapter.

Carroll, who was present at the Lennoxville massacre of 24 March 1985, was charged with first-degree murder for his actions during the massacre, but was acquitted in 1987. Besides Carroll, two other members of the Halifax chapter, Randy Mersereau and Mike McCrea, were also charged with murder and acquitted. During his time in a Montreal jail while he was trying to raise bail, Carroll learned passable French. When Carroll returned to Halifax after his time in a Montreal jail, he was so poor that he took to shoplifting groceries to feed himself.

In Halifax, he worked as a pimp and demanded 40% of all the earnings made by the local prostitutes. 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. On 30 May 1986, Carroll was arrested together with the seven members of the Halifax chapter and charged with living off the avails of prostitution. Carroll together with the other accused was convicted and sentenced to one year in prison. Prison psychiatric evaluations credited him with a genius intelligence quotient.The Fugitive: Hells Angels Hit Man David “The Wolf” Carroll Still On Run From The Law 20 Years Later Scott Burnstein, GangsterReport.com March 26, 2021 The arrests and convictions nearly put an end to the Halifax chapter because Hells Angels rules require that all chapters must have at least six active members at any given moment, and that any chapters with fewer than six members will have their charters revoked, meaning that all of the remaining members will be automatically expelled. With the arrests and convictions of the entire Halifax chapter for living off the avails of prostitution, Sonny Barger and the other American leaders of the Hells Angels were about to revoke the Halifax chapter's charter, leading Carroll to ask for the help of the Angel chapters in the Lower Mainland. In response, the Hells Angels in British Columbia sent out six of their members to Halifax to serve as temporary members of the Halifax chapter for an average of two weeks in rotation until Carroll and the others were released.

On 7 April 1988, Carroll was again charged with first-degree murder in 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. In 1990, Carroll moved to Quebec. He settled in Morin-Heights, a village in the Laurentian Mountains north of Montreal, where he lived with his French-Canadian common-law wife and their son. Despite moving to Montreal, Carroll retained control of the Halifax chapter. Carroll controlled a drug pipeline running from Halifax to Montreal. Carroll became the patron of Dany Kane in 1991 and in 1992 taught Kane how to fire a handgun properly.

Carroll wore the Hells Angels' "Filthy Few" special patch consisting of the SS lightning bolt runes. 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. The journalist Yves Lavigne wrote: "Only killers can wear the black-and-white Filthy Few patch and the black-and-white SS lightning bolts". In July 1993, Carroll along with Stadnick tried to have Frank "Cisco" Lenti, the president of the Loners gang, "patch over" to join the Hells Angels at a bikers' convention in Wasaga Beach, an offer that Lenti declined. During the 1993 Wasaga Beach convention, Carroll wore a custom-made black T-shirt with the white SS light bolt runes alongside the message "Filthy Few Denmark", which Lenti understood as Carroll's way of saying that he committed a murder in Denmark. In early 1994, Carroll help recruit Dany Kane of the Angels puppet club, the Evil Ones of Drummondville, to serve as the president of new puppet club in Toronto to be called the Demon Keepers. 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. Kane was so embittered by the failure that he turned police informer in October 1994. According to Kane in his reports to his police handlers, Carroll was in business with the Rizzuto family, owning a bar in Saint-Sauveur. By 1997, Carroll had purchased land to build condominiums in Saint-Sauveur and was the owner of several nightclubs in Montreal.

Quebec Biker War During the Quebec biker war, Carroll displayed a raging hatred of the Rock Machine as Kane reported that Carroll "seemed to take the [biker] war personally" and that for him "there did not exist any peaceful means to end the conflict". Kane described Carroll as "a very bad businessman... Wolf makes a lot of money but he can't keep it". In his reports, Kane described Carroll as a hard-drinking Hells Angel who was "chronically broke". Kane reported that he would visit Carroll in his house to discuss drug deals and then go out with the Carroll family to their favourite Vietnamese restaurant in Morin-Heights, saying he found the juxtaposition of criminality and domesticity to be quite jarring. 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. Kane, in his reports, stressed that Carroll displayed abnormal amounts of anger and hatred towards the Rock Machine. Kane reported that, along with Boucher, Carroll was the Hells Angel who had taken out the most contracts on the lives of Rock Machine members. In his reports, Kane described Carroll as personally collecting intelligence on the Rock Machine, which was unusual for a "full patch" Hells Angel.

In the first days of February 1995, Kane reported that Carroll had planted a bomb in Quebec City that cost one person their leg. Kane found himself in the middle of a power struggle between Carroll and another Hells Angel, an American living in Montreal named Scott Steinert. Kane in his reports stated that Steinert was the most aggressive of the Angels as Kane described Steinert as a bully with a belligerent and unpleasant personality. Steinert served as Maurice "Mom" Boucher's right-hand man as he made more money than any of the other Angels in Montreal. Steinert often mocked Carroll, boasting that he made more money than he did, and Kane reported that the two men hated each other. The journalists Julien Sher and William Marsden wrote that the feud between Carroll and Steinert was like "the twisting schemes of ambitious and sometimes psychotic medieval princes". When Carroll asked Kane to drive him to Halifax in March 1995, Steinert refused to allow it and the two men almost came to blows over the issue. Reflecting the power balance, Donald "Bam Bam" Magnussen, the bodyguard to Stadnick, went over to serving as Steinert's bodyguard as Magnussen believed that Steinert would soon be the new Hells Angels national president. Steinert formed a gang within the gang that he called the groupe de Cinq ("group of Five") that took over drug dealing along Crescent Street in Montreal and York Street in Ottawa, both of which were Carroll's territory. Steinert also started to sell drugs all over Quebec, Ontario and Manitoba, which both Stadnick and Carroll considered to be their territory.

Carroll also remained engaged with the Halifax chapter, which he regularly visited. On 25 June 1995, Carroll became a founding member of the Angels' elite Nomad chapter. Besides 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. The Nomads were led by a triumvirate with Carroll responsible for Atlantic Canada, Boucher Quebec and Stadnick the rest of Canada.
