WASHINGTON (DC News Now) — The Metropolitan Police Department (MPD) said Friday that the retired police lieutenant who fired a gun during training, killing a library police officer Thursday faced a charge of Involuntary Manslaughter.
Officers said they arrested 58-year-old Jesse Porter after consulting with the United States Attorney’s Office for the District of Columbia.
Police said Porter was conducting training inside the Anacostia Library Thursday afternoon. At the end of the training, Porter fired a gun. The bullet hit 25-year-old Maurica Manyan of Indian Head, Md.
Medics took Manyan, who was a library police officer, to the hospital where she died.
Detectives interviewed other library police officers, as well as Porter, Thursday. Their investigation found that Porter, working as a private contractor, was providing ASP Baton instruction. He and the trainees were in a conference room when he fired the gun.
Porter’s LinkedIn profile says he is the CEO of Chief Executive Officer of Porter Consulting and Expert Tactical Training, LLC. Porter was with MPD for more than 33 years, retiring from the force in 2020. Among the services the profile says he can provide are use of force instructor, de-escalation and crisis negotiator-intervention instructor, patrol tactics instructor, ASP instructor, and witness.
Porter recently appeared on Dan Abrams Live on NewsNation to discuss a deadly shooting in California that involved police.
