Notorious drug lord Alberto “Alpo” Martinez was fatally shot in Harlem, Upper Manhattan, New York City on Sunday, Oct. 31.

The drug kingpin was gunned down at around  3:30 a.m. while he was in his 2017 Dodge Ram at 147th Street and Frederick Douglass Boulevard, the New York Post reported authorities said. 

Martinez was in witness protection for testifying against other drug dealers in the crime ring to avoid a life sentence after his arrest in 1991 in Washington, D.C. The 55-year-old had served 35-year behind bars before being released in 2015.

It was not clear why Martinez was in the neighborhood where he used to operate his drug-dealing crimes back in the 1980s before being captured by the authorities.

A law enforcement source said Martinez was risking his life appearing in his old haunt, where he had accumulated enemies for testifying against his criminal compatriots.  

“You were in the witness protection program because you testified against other drug dealers,” the source said, according to the Post. “You’d make a lot of enemies who have a score to settle.”

The Daily News noted Martinez had been seen in the area back in 2019.

No instant arrest was made, and the police had not named any suspect.
