The marijuana package was later found on the street where Pressley was killed, according to court records.
In court, Pressley’s sister blamed Seward for the death of their 97-year-old father.
“He gave up, because you took his daughter’s life,” Elisha Hubbard said according to WPDE-TV, during Thursday’s sentencing hearing, adding that he loved the treats that Irene Pressley would bring him every day.
Seward listened carefully to Pressley’s family as they spoke at the hearing and stood up when the judge asked him if he wanted to speak.
Seward then said he didn’t “want to cause any more confusion. I don’t have anything to say, " the TV station reported.
The co-defendant who helped Seward look for the mail carrier was sentenced to 25 years in prison. Jerome Terrell Davis, 31, pleaded guilty to robbery and conspiracy to possess with intent to distribute and to distribute marijuana, prosecutors said.
The value of the marijuana in the package was minimal.
At the time of the murder, it would have cost around $1,600 ($2,604) in Colorado, where it was legal, according to state revenue data. Even when marijuana was illegal nationwide, the value of the package would not have exceeded $2,600 ($4,231), according to National Drug Intelligence Center data about South Carolina in 2000.
