Off-Duty Police Sergeant’s Cold Case Homicide Solved After 5 Years

4

Breaking the five-year silence, LA News Center reveals the thrilling arrest of Dion Thompson, a man accused of murdering Sergeant Tony Anthony Mason Jr., an off-duty Washington, D.C. police officer, in 2017.

The Unsolved Enigma

Sergeant Mason, a respected veteran of the Metropolitan Police Department, met a tragic end while sitting in a parked car with a companion. Details surrounding his demise remained shrouded in mystery, leaving his family and colleagues in anguish.

Rekindling the Flame of Justice

Just when hope seemed to dwindle, a crucial tip emerged early in 2023, propelling detectives back into the investigation. The trail led them to Thompson, who was 18 at the time of the shooting. Thompson is currently incarcerated in a federal prison, facing unrelated drug and firearm charges.

Motives in Shadow

While the charging documents do not definitively reveal Thompson’s motive, they paint a chilling picture of paranoia and violence. According to a cooperating witness, Thompson confessed to firing into the parked car after leaving his friend’s grandmother’s house. Disturbed by unfamiliar occupants, he allegedly feared robbery or retaliation for his own criminal activities.

The Ripple Effect

In a cruel twist of fate, Thompson allegedly learned of Mason’s status as a police officer only after watching the news. Detectives believe he then fled to Philadelphia to dispose of the vehicle used in the shooting.

Innocent Victims Wrongfully Targeted

Tragically, the attack also left Mason’s companion injured. The charging documents implicate two additional suspects in the shooting, one of whom has since passed away in a car accident. No other charges have been filed in the case to date.

A Fallen Hero

Sergeant Mason, a 17-year veteran of the police force, was a beloved figure in the community. He was unarmed and without any identifying law enforcement garb at the time of the attack. Background checks revealed no criminal or gang associations involving either Mason or his companion.

Justice Served

The arrest of Thompson marks a significant milestone for the Washington, D.C. police department and the family and friends of Sergeant Mason. “For far too long, the details surrounding Sergeant Mason’s tragic death have remained a painful mystery,” said Chief Pamela Smith. “While we cannot erase the pain of loss or the memories of that day, we can take solace in the fact that the person responsible is being brought to justice.”

Dawn of a New Era

This case marks the inaugural prosecution brought by Baltimore State’s Attorney Ivan Bates’ newly established Cold Case Unit, signaling a renewed commitment to solving unsolved crimes and bringing justice to victims’ families.
