A murder conviction that’s already been handed down twice was reaffirmed by a state appeals court Tuesday.

Thomas J. Campbell , 52, of Wilmington, Del.,  was found guilty in 2003 of fatally stabbing 45-year-old George S. Jackson II of Woodbury and critically wounding 37-year-old Kimberly Love, who Jackson had been visiting in West Deptford, on Jan. 11, 2000.

Campbell was sentenced to 30 years for murder and 20 years for attempted murder.

That conviction  was upheld in 2005 by an appellate court, and the state Supreme Court declined to hear the case. The appeals court remanded the case to Superior Court for resentencing, but the same sentence was imposed in 2008 and that sentence was also unsuccessfully appealed.

Campbell filed a petition for post-conviction relief, claiming there were errors in jury selection and that the had ineffective legal counsel. The conviction was again upheld.

Campbell appealed the post-conviction relief decision, and that led to today’s further affirmation of the original sentence.
