Citing an "unprecedented number" of threats against his department, Baltimore County's police chief says he will not identify the officer who fatally shot a woman after an hourslong standoff at her apartment.

A department news release on Thursday says Jim Johnson also cited the recent killings of police officers in Dallas and Baton Rouge, Louisiana, as a factor in his decision.

Police say 23-year-old Korryn Gaines was fatally shot Monday in her Randallstown apartment when she pointed a shotgun directly at an officer. Gaines' 5-year-old son, who was in the apartment, was injured.

The police department, in accordance with its agreement with the Fraternal Order of Police, waits 48 hours after a shooting to identify the officers involved.

Johnson says the department has received threats against specific officers and officials.
