A Richmond man has been indicted on murder charges in the 2023 ambush killing of 19-year-old Da'Troy “Puddybo” Moore, a community outreach worker who was gunned down outside the Monterey Pines Apartments just three days after his birthday. Amilliyon Hackett-Addison, who was 18 at the time of the shooting, has spent the past two years behind bars awaiting trial and is due back in court in mid-November.
According to The Mercury News, Moore was killed on November 23, 2023, when Hackett-Addison allegedly waited outside the Monterey Pines Apartments on South 37th Street in Richmond before opening fire. Family members said around 15 shots were fired, according to Moore's obituary, and Moore reportedly yelled “stop” as he was being killed. He was the father of a young daughter.
A grand jury heard testimony from 34 witnesses before returning the indictment, which charges Hackett-Addison with murder, shooting at an inhabited dwelling and possessing a stolen red Infiniti Q50, the outlet reported. He is awaiting trial.
The Case Has Not Been Decided
Hackett-Addison has pleaded not guilty, and the allegations have not been proved at trial. The Contra Costa Superior Court says defendants in criminal cases are presumed innocent unless proved guilty beyond a reasonable doubt.
Gang Allegations and a Life-Without-Parole Enhancement
Prosecutors also allege Hackett-Addison belonged to Richmond's Crescent Park gang and that the killing was intended to promote, further and assist criminal conduct by gang members, according to the report. Law enforcement targeted the group in a 2017 operation known as Crescent Moon; the gang has reportedly existed in Richmond for decades.
The murder charge also carries a special-circumstance allegation of lying in wait. Under California Penal Code Section 190.2(a)(15), an intentional murder committed by means of lying in wait carries a sentence of death or life imprisonment without the possibility of parole. If convicted, Hackett-Addison could face life without parole.
The Crescent Park housing complex has its own troubled history. In August 2023, just months before Moore's killing, a suspect led a high-speed chase before barricading himself at the South Richmond property, according to the SF Standard.
A Life Devoted to Outreach Work
Moore's death deeply affected the organization where he worked as a community ambassador in San Francisco's Tenderloin neighborhood, according to a statement from the program. Manager David McKinley said Moore quickly formed friendships with others in the program. Moore was described as dedicated to the program, his daughter and his future.
The Community Ambassadors Program launched in Bayview in 2010, when Ed Lee was city administrator; Lee helped develop the pilot and expanded it after becoming mayor in 2011, as Hoodline previously reported. Ambassadors like Moore perform street-level assistance, connect residents with services, and support neighborhood safety — work that stands in stark contrast to the violence that ultimately took his life just across the bay in Richmond.
Federal Lawsuits Over Jail Conditions Dismissed
While awaiting trial, Hackett-Addison filed two federal lawsuits against the Contra Costa Sheriff's Office. One alleged he was placed on lockdown over an issue involving a previous cellmate, while another demanded $80,000 over his placement in a cell with a broken toilet. Both lawsuits were thrown out, the Mercury News reported.
The complaints echo longstanding concerns about custody conditions in Contra Costa County's jail system. In October 2020, the county agreed to spend $250 million over five years to settle a lawsuit brought by the Prison Law Office alleging inadequate medical care in its jails, according to CBS News.
A Killing Amid a Broader Decline in Violence
Moore's murder occurred amid a period when Richmond was still grappling with elevated violent crime even as homicides trended downward. In 2024, violent crime in Richmond rose 7% overall while the police department operated with 20 vacant sworn positions out of 146 budgeted officer roles, according to Contra Costa News.
California's homicide rate fell 10.4% in 2024, while homicide rates across 30 major U.S. cities tracked by the Council on Criminal Justice dropped 17% in the first half of 2025 compared to the same period the year before.
