The 53-year-old Arroyo faces 30 years in prison under his plea agreement with Monmouth County prosecutors.
Authorities say Arroyo picked up 25-year-old Lateea Holmes and then strangled the Long Branch woman. Her partially clad body was found in a wooded area in Neptune last October.
In admitting to the killing, Arroyo said he could recall little of what he did because he was drinking.
Prosecutors say the killing had a chilling similarity to Arroyo's killing of Melinda Moran in 1992.
