Brett Cantor

The LAPD detectives assigned to the Cantor case at the time Bosco inquired about it also denied any connection. Dallas-based author and private investigator William Dear likewise asserted in his 2014 book O.J. Simpson Is Innocent And I Can Prove It that Cantor was a diversion by the Simpson defense to protect Simpson's son Jason. Bosco stated that Cantor was under investigation by the FBI for possible involvement in the drug trade at the time of his death, and one of Jason's former girlfriends told Bosco that investigators found $130,000 in cash in a safe in Cantor's office after he was killed.

Edelson could not bring himself to enter Dragonfly after Cantor's death, and sold his interest shortly afterwards. "Being there felt wrong, and it still does today" he told Los Angeles magazine in 2012. Cliff Cantor took over his brother's share and ran the club afterwards.

Simpson's defense, which admitted at the time it requested the files that they weren't sure there was a connection, never brought the Cantor killing into evidence. Simpson was subsequently acquitted in October 1995. After the trial, author Joseph Bosco followed up on the Cantor homicide in his book A Problem of Evidence. He reported that the Cantor family had set up a tip hotline for information about Brett's death, but had it directed to them rather than the LAPD, and only shared one tip they received, which did not produce any useful leads. Cantor's family has publicly dismissed any connection between Cantor's death and the Simpson case; privately, Bosco wrote, the wife of Brett’s other brother Matt, told him she believed there was a connection between the cases.

In September 1994, Simpson's lawyers moved to have Judge Lance Ito allow them to review the LAPD's file on the Cantor homicide. Like Cantor, Nicole and Goldman had been stabbed predominantly in the upper body, their throats severely cut. Goldman's throat, in particular, had been cut by someone reaching from behind him, starting on the left side and moving upward to the right across the neck, similar to the wound on Cantor. According to the coroner, the killer of Nicole and Goldman had also used a long thin blade, much like the one that had been used on Cantor.

Cantor was found dead in his Hollywood home on July 30, 1993; he had been stabbed repeatedly in the upper body. No suspect has ever been identified and the investigation remains open. His death was the subject of renewed interest a year later, when, during preliminary motions in the trial of O. J. Simpson for the killings of his former wife, Nicole Brown Simpson, and Ron Goldman, Judge Lance Ito ruled that defense lawyers could have access to the investigatory file in the Cantor case. The defense had argued that the similarity of the three killings suggested the same person or persons had committed them. It has also been argued in books on the case that Cantor knew both Goldman and Nicole, and thus they may have been killed over mutual involvement in possibly illegal business activities.

One spring 1993 night at Dragonfly Cantor met a young actress named Rose McGowan. The two soon became romantically involved; in her 2018 autobiography Brave, McGowan credits him with helping her escape an abusive relationship that had led her to develop an eating disorder. She considered him her soul mate.

Early on the morning of July 30, 1993, Cantor left another nightclub, Club 434. He is not known to have been seen alive after that. Later that day, his body was found at his Hollywood home a short distance from Dragonfly.

At Chrysalis Music Group, Cantor worked as an A&R executive, looking for artists to sign and develop. In that capacity he signed Jane's Addiction and helped get Rage Against the Machine its first record contract. Both bands became stars of the early 1990s alternative rock scene.

After signing Rage Against the Machine, Cantor left Chrysalis to work briefly as an agent and then a promoter, putting together some of the largest concert and dance events in the city at that time. He also entered the nightclub business, taking a 10% stake in Dragonfly, a club known at the time for its 1970s and hip hop theme nights. At that time he was involved romantically with actress Rose McGowan.

When nightclub owner Steve Edelson converted one of his Frolic Rooms, on Santa Monica Boulevard in Hollywood, into a different club called Dragonfly, Cantor came in as his partner, holding a 10% share in the business. Dragonfly soon became known among the city's clubgoers for its theme nights. Wednesday nights were part of a series called Superfly, focusing on 1970s music, particularly disco, while Friday night's Riot featured hip hop. The club was profitable for its owners.

Brett Ross Cantor (November 5, 1967 – July 30, 1993) was an American record label executive, concert promoter and nightclub owner. He was born in New York to Rhonda and Paul Cantor, who managed acts such as B. J. Thomas and Dionne Warwick. In the early 1970s, he and his family moved to the Los Angeles area. In the early 1990s, he served as an A&R executive for the Chrysalis Music Group.

Cantor was born in New York in 1967. His father Paul, a former William Morris agent who had moved into managing musicians like Dionne Warwick and B. J. Thomas, moved the family to Los Angeles four years later. In his young adulthood, Brett followed his father and older brothers Cliff and Marc into the music industry.

Ito granted the motion three weeks later, ruling that the material was "discoverable under Brady", referring to the 1963 U.S. Supreme Court decision that requires prosecutors to turn over any potentially exculpatory evidence their investigations uncover to the defense. The Simpson defense team also noted that the similarity of the killings themselves was not the only connection between the three murders. Goldman had once worked at Dragonfly as a waiter, where he was seen together with Cantor by other employees, and Nicole had often gone there with her friends to dance, raising the possibility that either or both were acquainted with Cantor.
