"LAPD officer David Mack was convicted of the November 1997 theft of $722,000 from a Bank of America branch in Los Angeles. Two days after the bank robbery, Mack took a gambling trip to Las Vegas with two other police officers, including Raphael Perez. In the course of investigating the bank robbery, detectives developed leads that caused them to believe, at the time, that Mack was a possible suspect in the 1997 murder of east-coast rap star, Biggie Smalls, a.k.a., the Notorious B.I.G. Mack is currently serving a 14 year sentence and has reportedly claimed association as a Piru Blood, an L.A. gang with ties to Death Row Records. He was sentenced to 14 years and three months in federal prison.[1] Mack has never revealed the whereabouts of the money.
David Mack grew up in the same Compton neighborhood as Suge Knight.[2] A remarkable athlete, Mack won a scholarship to the University of Oregon, where he ran track and eventually made the United States national team running the eight hundred metres.[3][2] Mack joined the LAPD in 1988. He was married with two kids.
Mack is a member of the Bloods, a gang with ties to Death Row Records. Mack was hired as an off-duty body guard for Death Row Records by Death Row Founder Marion "Suge" Knight, also a Blood. Investigating LAPD detective Brian Tyndall believes David Mack was involved in the conspiracy to kill rapper Notorious B.I.G..[4] Mack was named in the April 16, 2007 wrongful death lawsuit filed by the rapper's family against the city of Los Angeles.[5]
Mack has refused to cooperate with police, and bragged to fellow prisoners that his $700,000 bank score is invested in such a way that it will double by the time he concludes his 14 year sentence.[2] While in prison, Mack has severed his ties with police and become an avowed member of the Bloods street gang. Mack's jailers report he uses a red toothbrush, wears red socks, and as much red as can be attained in a federal prison. According to former LA Police Chief Bernard Parks, "It appears he has completely divested himself of all relationships of his life as a police officer. He is basically a gang member. He has taken on the role of being a gang member in jail."[2] Mack apparently had a gang-related confrontation while in prison that resulted in his being stabbed.[6]
