LITTLE VALLEY — A 31-year-old Salamanca man convicted of first-degree assault in the strangulation death of Chad Skoken in 2020 was sentenced to 18 years in state prison in Cattaraugus County Court on Monday.

Derrick C. Marsh, of Waite Avenue, Salamanca, was also sentenced by County Court Judge Ronald Ploetz to five years’ post-release supervision on the first-degree assault charge, a class B felony.

A jury found Marsh not guilty of all other charges including second-degree murder, tampering with physical evidence and concealing a corpse on May 14.

District Attorney Lori P. Rieman said she believes Marsh and Skoken, who were neighbors, were fighting when Jeremiah Des Jarlais, 35, of 37 Waite Ave., placed a garrote over Skoken’s neck. Marsh then ran away and was not present when Skoken was murdered by Des Jarlais.

Des Jarlais was convicted in June of all charges — second-degree murder, first-degree assault, first-degree strangulation, tampering with physical evidence and concealing a corpse — after a separate trial in the death of Skoken.

Des Jarlais will be sentenced next month.

Skoken was found dead by police Jan. 12 in a garage at 37 Waite Ave., following an investigation by the Salamanca Police Department. The investigation led police to believe an altercation had taken place between the three about 24 hours before Skoken’s body was discovered.

Marsh and Des Jarlais were arrested after an investigation by Salamanca Police and Cattaraugus County sheriff’s investigators.
