MD Security Guard Pleads Guilty To Shooting Boss After Being Reprimanded

ANNE ARUNDEL COUNTY, MD — A Pasadena man pleaded guilty Thursday to fatally shooting his supervisor after being reprimanded at work.

Dylan Blake Chandler, 27, was facing second-degree murder and using a firearm in a violent crime. Both charges were in connection to the fatal workplace shooting in January.

A release issued by the Office of the State's Attorney states Chandler shot his supervisor, 37-year-old Joseph Keith Aman, moments after being confronted about "workplace performance issues."

The deadly incident occurred Jan. 28 as the two were in the supervisor's office. Anne Arundel County Police were called to the scene shortly before 3:30 p.m.

Chandler had been working as a security guard at a Northrop Grumman facility at 7323 Aviation Blvd. in Linthicum. He was not directly employed by the defense firm, but rather through a security contractor.

Aman was pronounced dead at the scene after suffering from single gunshot wound to the head. Chandler was disarmed and restrained by a coworker who reported seeing the Pasadena man pointing a firearm at Aman, the release said.

Through the course of the investigation, Chandler admitted to homicide investigators that he had "snapped" before fatally shooting Aman.

"Investigators believe the defendant did not premeditate or plan to commit murder, but rather killed the victim following being reprimanded for workplace conduct," State's Attorney Anne Colt Leitess said in a statement.

"This is a horrible tragedy. My heart goes out to the family of Mr. Aman, who have suffered a devastating loss due to this defendant's irrational actions."

Chandler is scheduled for sentencing on Dec. 15.
