A Washington man charged in the Feb. 8 shooting death of an off-duty Prince George's County policemen in Iverson Mall pleaded guilty yesterday to first-degree murder.

Terrance A. Harris, 21, entered the guilty plea before Prince George's Circuit Court Judge Howard Chasanow, who will sentence Harris on Oct. 15.

Harris was one of four men charged in the death of Raymond Hubbard, 28, who was killed when he attempted to stop a robbery of a jewelry store in the Marlow Heights mall.

One of the four, Ronald Drake, 24, also of Washington, was found guilty last week of murder in Hubbard's death and of armed robbery of a Safeway store on Feb. 5. Both Harris and Drake were residents of a halfway house at 1010 North Capitol St. NW.

State's Attorney Arthur A. Marshall Jr. said that, in exchange for the guilty plea, Harris will not be prosecuted for the Safeway robbery, in which he also was charged. Neither will the state seek surgical removal of a bullet that lodged in Harris' back, an operation that Harris feared, Marshall said.

Harris was arrested after he sought treatment at Howard University Hospital shortly after the shooting.
