Security guard Joseph Keith Aman killed in Northrop Grumman shooting
On January 28, 2026, at approximately 3:30 p.m., officers assigned to the Northern District responded to a reported shooting at the Northrop Grumman facility located in the 7300 block of Aviation Boulevard in Linthicum, Maryland.
Upon arrival, officers determined that the scene had already been secured by the Maryland Transportation Authority Police (MDTA), who had the suspected shooter in custody.
Preliminary findings indicate the incident stemmed from a dispute between two contracted security guards working inside the facility.
During the altercation, one of the guards discharged a firearm, striking the other.
The victim was identified as 37-year-old Joseph Keith Aman of Baltimore, Maryland. He sustained fatal injuries and was pronounced dead at the scene.
Authorities stated that a third contracted security guard intervened during the incident, successfully disarming the suspect and detaining him until law enforcement arrived.
Investigators confirmed the shooting was an isolated incident and did not involve any Northrop Grumman employees.
There was no ongoing threat to the public or the facility following the incident.
Anne Arundel County Police Department Homicide Unit detectives responded to the scene and assumed control of the investigation.
Detectives conducted multiple witness interviews, while Evidence Collection Unit technicians processed the scene and recovered the firearm believed to have been used in the shooting.
The suspect was identified as 26-year-old Dylan Blake Chandler of Pasadena, Maryland.
He has been formally charged with first-degree murder, second-degree murder, and additional related offenses.
Northrop Grumman issued a statement acknowledging the incident, saying:
“We are aware of an isolated incident involving two contractors at one of our Baltimore-area facilities. We are cooperating fully with local law enforcement as they investigate the matter. The safety of our employees and contractors across all facilities remains our top priority.”
The investigation remains active and ongoing.
Although an arrest has been made, detectives are continuing to gather information.

Investigators Believe Nancy Guthrie Removed From Her Home and Likely Concealed or Disposed of Within a Two-Hour Drive
TUCSON, Ariz. — As the investigation into the disappearance of Nancy Guthrie continues, analysis of the known timeline suggests she was most likely removed from her residence between approximately 2:30 a.m. and 3:00 a.m. local Tucson time.
Based on that estimated window, investigators and independent analysts believe that if Guthrie was transported from her home, the suspect would have had sufficient time to conceal her or dispose of her remains within a two-hour driving radius of Tucson before first light.
Twilight on Sunday, February 1, 2026, began at approximately 5:40 a.m., providing a limited but significant period of darkness during which a suspect could have traveled undetected.
This geographic radius would encompass large areas of remote desert terrain, rural roadways, mountainous regions, and sparsely populated land across southern Arizona.
Law enforcement has not publicly confirmed a specific search zone but has emphasized that remote areas remain a focus of investigative efforts.
The Federal Bureau of Investigation and the Pima County Sheriff’s Department have been working jointly on the case.
As previously announced, federal authorities recently released four images recovered from Nancy Guthrie’s home surveillance system, including images depicting a masked individual believed to be connected to the case.
Investigators have stated that over the course of eight days, they worked closely with private-sector technology partners to recover digital evidence that may have been lost, corrupted, or rendered inaccessible. Authorities indicated that certain recording devices may have been removed from the home, complicating early evidence collection efforts.
Officials have not publicly confirmed whether Guthrie is deceased, and the case remains classified as a missing person investigation. However, the working theory that she was forcibly removed from her residence during the early morning hours has guided search efforts.
Investigators have emphasized that locations where a victim may have been concealed or transported could still contain critical forensic evidence. If Nancy Guthrie was taken to a secondary location within the estimated timeframe, it is possible that trace evidence — including DNA belonging to both the victim and the perpetrator — could remain recoverable.
Identifying any site containing a combination of Nancy Guthrie’s DNA and that of a suspect would represent a significant breakthrough in the case and could substantially assist law enforcement in determining what occurred.
Authorities continue to urge anyone with information about Nancy Guthrie’s disappearance to come forward. Even seemingly minor details — including unusual vehicle activity, suspicious behavior, or knowledge of remote locations accessed during the early morning hours of February 1 — could prove vital.
Anyone with information related to the case is asked to contact the FBI at 1-800-CALL-FBI.
The investigation remains active and ongoing.
