FREDERICK, Md. (DC News Now) — Officers said a person wanted for violating parole or probation refused to put down a knife when they confronted him Saturday night, prompting them to open fire, killing him.

Police Chief Jason Lando said officers with the Frederick Police Department went to an apartment complex in the 1500 block of N. East St. around 6:20 p.m. to see if they could find the person wanted for the violation. They went to a unit there where a lady opened the door. The officers went into the apartment and found the wanted man in a closet. Lando said he pulled the knife and that officers told him to put it down multiple times, but he didn’t. That’s when the police shot him. Lando added that the officers provided medical aid to him immediately and called for an ambulance, but he died.

The Frederick Police Department contacted the Maryland Attorney General’s Office. Its Independent Investigations Division (IID) and Maryland State Police (MSP) were taking over the investigation.

The Maryland Attorney General’s office released a press release on Sunday saying it is investigating the fatal officer-involved shooting.

The press release said they will generally release the name of the man that died and discharge officers within 48 hours of the incident, but that period may be extended if there is a specific reason to believe that an officer’s safety is at risk.

It also said that all of the officers on the scene had body-worn cameras, which recorded the incident. The Attorney General’s office said they generally release body camera footage within 14 days of an incident, but there may be situations where more than 14 days is necessary, including if investigators need more time to complete witness interviews.
