FREDERICK COUNTY, Md. (DC News Now) — The Frederick County Sheriff’s Office said three deputies were involved in a shooting Tuesday morning after they responded to a double stabbing. The suspect and one of the people who was stabbed died.

The stabbing occurred in the 5800 block of Haller Pl. around 2:10 a.m. Deputies and members of Frederick County Emergency Medical Services (EMS) found two people who’d been hurt.

The sheriff’s office said the call about the stabbing came from a woman claiming her brother was attacking their parents inside their home. Deputies found the mother inside the house. A team flew her to R Adams Cowley Shock Trauma, but her injuries were superficial. The father was down the street. Medics took him to Frederick Health Hospital, but he died on the way there.

Three deputies arrived and found the suspect armed. They fired their guns. The suspect died. FCSO detectives located a weapon on the scene.

The Maryland Attorney General’s Office Independent Investigative Division (IID), with assistance provided by the FCSO, will conduct the investigation into the three deputy’s actions. Both the homicide and the deputies-involved shooting remain an ongoing investigation.

The body camera footage is expected to be released within the next two weeks while the incident is under investigation by the Attorney General.
