District Woman Sentenced To 16 Years In Prison

On Charges in Two Stabbings, Including One That Killed a Man
-Attacks Took Place in Northeast Washington-

     WASHINGTON – Quindetta Cosby, 49, of Washington, D.C. was sentenced today to 16 years in prison for carrying out two stabbing attacks last year in Northeast Washington, including one that killed a man, U.S. Attorney Ronald C. Machen Jr. announced.

     Cosby pled guilty in November 2012 to one count of voluntary manslaughter while armed and one count of felony assault with significant bodily injury. She was sentenced by the Honorable Thomas J. Motley. Upon completion of her prison term, Cosby will be placed on eight years of supervised release.

     In the fatal attack, according to the government’s evidence, on Sept. 13, 2012, Cosby got into an argument at about 6:20 p.m. with the victim, Paul Morris, in the 2200 block of Fourth Street NE. Cosby’s friend also got involved in the argument, which escalated into a physical fight. Mr. Morris, 49, and Cosby’s friend threw punches at each other. Cosby joined the fight, which her friend was losing, and hit Mr. Morris. Mr. Morris struck Cosby, knocking her down.

     Cosby then pulled out a knife and stabbed Mr. Morris in the left side of his upper torso.  Mr. Morris fled into the 300 block of Bryant Street, NE, while dripping blood from the stab wound. Cosby chased Mr. Morris while screaming threats to kill him. When Mr. Morris retreated to a porch on the street, Cosby kept following him, threatened again to kill him, and stabbed him on the porch.  Mr. Morris died shortly thereafter. 

     The other attack took place on July 16, 2012. In that incident, Cosby got into an argument with a woman in an apartment in the 600 block of Edgewood Street NE. The argument spilled into the hallway, where she pushed the victim to the floor. Cosby attacked the victim with a knife, resulting in a significant cut to the victim’s arm.

     In announcing the sentence, U.S. Attorney Machen commended the work of the detectives and officers of the Criminal Investigations Division and the Fifth District of the Metropolitan Police Department.  He also expressed appreciation to those who worked on the case from the U.S. Attorney’s Office, including Assistant U.S. Attorney Bridget Fitzpatrick, Victim Witness Advocate Tamara Ince and Paralegal Specialist Marian Russell.  Finally, U.S. Attorney Machen praised Assistant U.S. Attorney Shana Fulton, who prosecuted the case.
