Darryl Jackson, an inmate at Richland Correctional Institute, pleaded guilty this morning to manslaughter and felonious assault in the Sept. 20, 2003, stabbing death of Garland "Pookie'' Marshall. Summit County Prosecutor Sherri Bevan Walsh said in a release this morning that Jackson, 31, is scheduled to be sentenced at 1 p.m. in Judge Judith Hunter's courtroom in Summit County Common Pleas Court.

Marshall, 33, was found dead at his home by police responding to a call. Marshall had been stabbed more than 30 times.

A breakthrough in the case came in September 2006 when the FBI Laboratory's Combined DNA Index System (CODIS) matched Jackson to DNA recovered on the linoleum floor of Marshall's residence. Jackson was in prison on an unrelated charge.
