Police trainer charged after he reportedly shot and killed a woman while pulling out his pistol to show how quickly it could be drawn

• A retired DC police officer was charged with involuntary manslaughter on Friday. 
• Jesse Porter was conducting training for officers at a DC library when he allegedly shot and killed a 25-year-old woman. 
• Porter drew his pistol as a demonstration to show how quickly it could be done when he allegedly shot the woman in the chest, NBC Washington reported.

A retired Washington DC police lieutenant turned trainer allegedly shot and killed a fellow cop at a DC library during a training session on Thursday, police say. 

During the training for officers at Anacostia Neighborhood Library, Jesse Porter allegedly pulled out his pistol to show how quickly it could be drawn, and fired a shot that hit 25-year-old Maurica Manyan in the chest, NBC Washington reported.

Porter, 58, has been charged with involuntary manslaughter, according to DC police. 

At a press conference after the shooting, DC Police Chief Robert Contee said he wasn't sure why Porter had a live weapon during the training session.

"It's not good practice to do that," Contee said.

Porter worked in the DC Police Department for 33 years before retiring in 2020, according to a LinkedIn profile. He runs his own training and consulting company for cops.
