Press Release

Defendant Brutally Beat Victims with a Shovel and Sledgehammer at Northeast Warehouse

WASHINGTON - Vincent Hemphill, 63, of Washington, D.C., was sentenced today in D.C. Superior Court to a total of 300 months in prison for killing an 80-year-old colleague and attempting to kill two others at a warehouse owned by the Washington Air Compressor Rental Company, announced U.S. Attorney Matthew M. Graves and Chief Pamela A. Smith, of the Metropolitan Police Department (MPD).

Mr. Hemphill pleaded guilty on September 6, 2024, to one count of voluntary manslaughter while armed and two counts of assault with intent to kill, in the Superior Court of the District of Columbia. In addition to the prison term, Superior Court Judge Erik Christian ordered Hemphill to serve 11 years of supervised release.

According to the government's evidence, on October 12, 2023, Hemphill was at work at the Washington Air Compressor Rental Company's warehouse, located at 1800 4th Street Northeast, Washington, DC. The defendant was directed by his work supervisor, Brian Jefferson, to move an air compressor. Hemphill did not immediately retrieve the requested air compressor and Mr. Jefferson, again requested, over the loudspeaker system, that he retrieve the air compressor. The defendant carried a large metal shovel to Brian Jefferson's office and hit Mr. Jefferson in the head with it while Mr. Jefferson was seated at his desk and unable to move due to a prior injury to his foot. At the time Hemphill attacked Mr. Jefferson, Mr. Jefferson could not move around without the use of a scooter.

The defendant then chased Charles Short, one of his co-workers, and, as Mr. Short tried to escape from him, Hemphill began to hit Mr. Short with the shovel. Hemphill continued to strike Mr. Short with the shovel repeatedly after Mr. Short had collapsed to the ground. The defendant then turned his attention to Jacob Othman, another co-worker, and hit Mr. Othman with the shovel. Mr. Othman was able to take the shovel away from Hemphill and began to run from the defendant but collapsed to the ground. Hemphill chased after Mr. Othman with a sledgehammer and struck Mr. Othman with the sledgehammer. The defendant then returned to where Mr. Short was lying on the ground and hit Mr. Short with the sledgehammer in the back and head area.

Jacob Othman suffered from lacerations to his head and serious injuries to his shoulder. Brian Jefferson suffered from serious lacerations to his head, a brain bleed, a concussion, and a fractured jaw. Mr. Short suffered from severe lacerations to the head and facial area, orbital fractures, and a fractured mandible. Mr. Short succumbed to his injuries and died on January 22, 2024. The complications sustained from the assault precluded Mr. Short from returning to his baseline health and the manner of his death was ruled a homicide.

In announcing the sentence, U.S. Attorney Graves and Chief Smith commended the work of those who investigated the case from the Metropolitan Police Department. Finally, they commended the work of Assistant U.S. Attorneys Benjamin Helfand and Lauren Galloway, who investigated and prosecuted the case.
