Combs, known to friends as “Buttons” was found in April 2016 beaten to death in a trailer located at an abandoned business.

A familiar and well-liked figure in Swedesboro, police began to search for Combs based on a report that the had not been seen for days.

Following an investigation, officials said that he sustained multiple head injuries and died from blunt force trauma.

Investigators linked Tyson to the murder of 60-year-old Sylvester Combs through evidence found at nearby arson seen in Swedesboro.

Gloucester County Prosecutor Sean Dalton said there was no link between the arson and the murder and the two men were nothing more than acquaintances.

“As far as why he did it, only he and, unfortunately, Mr. Combs know what happened,” said Dalton after the investigation.

A week before Tyson’s March 2017 hearing, Comb’s brother-in-law, Alfred Lee, said he was grateful Tyson had been charged.

Tyson was also sentenced on pleas of conspiracy to commit arson in the burning of a storage shelter trailer at a Swedesboro cemetery.

He will be ineligible for parole until he serves 85-percent of his sentence.
