Love Emmanuel Luberesse, 23, appeared in court this afternoon on charges of second-degree murder.
Police arrested Luberesse at a building near the intersection of Ste-Catherine Street and Stanley Street.
Witnesses told police a fight broke out after Pellicano lost his necklace and asked for someone to turn down the music so people could help him find it.
Police say he was stabbed at least once and he was dead by the time paramedics arrived at the scene.
It was Montreal's second homicide of the year.
