Former New York drug kingpin Alberto “Alpo” Martinez, who was killed Oct. 31, was tossing baggies of drugs out his truck window while driving away from gunfire in the drive-by shooting that took his life, The New York Post reports.

Baggies were discovered on the street spaced out a few feet apart in an apparent effort not to have them in his possession when the police arrived, the Post reported, citing an unnamed source, which also noted that he had been in a federal witness protection program and may have been trying to circumvent being arrested because he knew police would be arriving.

A crime scene video purports to show Martinez’s effort to get rid of what appeared to be heroin in the baggies. It was not immediately clear if he had been released from the witness protection program or if he was simply visiting his old neighborhood.

Martinez, 55, died on Oct. 31 while sitting behind the wheel of his Dodge Ram truck in Harlem. At the height of the crack cocaine epidemic, he was at the top of a drug empire that stretched from New York to Washington, D.C.

He was arrested in 1991 by the FBI and D.C. police as he drove his truck in Southeast Washington, The Washington Post reported. He was wanted for drug trafficking and drug-related killings.

Ultimately, he confessed to 14 murders but became a government witness who testified against his underlings. One of the murder victims was his longtime friend and partner in crime Rich Porter, who Martinez believed was cutting in on drug deals.

One of Martinez’s associates shot Porter for the crime bosses. When Porter didn’t immediately die, Martinez confessed that he “shot him in the head,” The New York Times reported.

Authorities released Martinez from prison in 2015 while serving a 35-year sentence. Martinez, who was in a government witness protection program, was last known to live in Maine,

His notorious exploits inspired the 2002 classic film Paid in Full. It featured rapper Cam’ron as Martinez and Mekhi Phifer, who portrayed Porter.
