See Giordano's post on page 1 of this thread for the mention of Tony Gensale, who was murdered on November 15, 2012. The French-language article at the link below states Gensale was killed because the shooter(s) believed him to be Giuseppe Fetta, the true target of the hit.

Two crimes committed in broad daylight, just 20 meters away, a month apart. December 17, 2012, Giuseppe Fetta was suffering from several gun shots near his car parked on the boulevard Saint-Laurent Street between Fleury and Sauriol. He survived the shooting. On November 15, gunmen had mistaken Tony Gensale, who died after being shot three times in the chest, leaving a taekwondo school, almost the same place.

Tony Gensale was shot by mistake, on November 15, Boulevard Saint-Laurent. His killers have taken to the mafia Giuseppe Fetta, riddled with bullets a month later, 20 meters from where Gensale took his last breath.

This is the hypothesis which now looking to investigators Division Major Crime Police of the City of Montreal (SPVM), that according to reliable sources revealed to Le Journal.

Referred to crimes committed in similar circumstances, both Montrealers of Italian origin were used in the same sector of Saint-Laurent Boulevard in the Ahuntsic-Cartierville borough, who took on the appearance of far west in recent months of 2012.

The draw will be wanted the real target whose head was a price he survived when his turn came, December 17.

Mobile unknown

"They got the wrong guy," police sources have suggested two's murder Gensale committed in broad daylight, on November 15.

Asked to comment, Commander Ian Lafreniere said simply that "the motive for this crime remains unknown" SPVM.

At 2:25 pm, Gensale, aged 43, came to Elite Taekwondo School, which he attended for several years, when an altercation broke out with at least two men who police suspect to be linked to street gangs. One of them whipped out a gun and hit the victim three times in the chest.

Gensale was known to police, but was "not a criminal of high rank," according to our sources. He had in his file a sentence of six months in prison in 2004 for cocaine trafficking.

Two incidents

December 17, 10:10 am, Giuseppe Fetta, 33, was next to his car - parked 20 meters from where Gensale died - when the hooded man shot him.

This unusual proximity between two crime scenes immediately investigators to believe that these cases could be linked.

Fetta, a tough guy who had recently risen in rank in the Italian mafia - the RCMP had identified as the bodyguard of mobster Francesco Arcadi during the Coliseum investigation - has been achieved in the legs and chest, but it is remained conscious during transport to the hospital. He has not shown talkative with the police, according to our information.
