State police say 21-year-old Jermaine M. Zachary of Dover was arrested Monday after reporting to his probation officer. He was charged with second-degree murder and attempted robbery in the September 2009 killing of 40-year-old Robert Watkins of Seaford.
Zachary is being held on $302,000 cash bond.
Zachary's arrest came after detectives reopened their investigation into the death of Watkins, who was killed after he and a friend went to a house in Magnolia to buy a dog. As the two were sitting in their car, Zachary got in the back seat. Another man approached car, pulled a pistol and demanded money from Watkins, who was shot as he and the friend tried to drive away.
