Oscar Prior-Ramirez of Eatontown faces a 27-year state prison term when he's sentenced on Feb. 7, 2014. He will have to serve about 24 years before becoming eligible for parole.

Prior-Ramirez initially was charged with first-degree murder in the death of Viridiana Beltran-Gomez, a 26-year-old Red Bank resident who went missing in May 2011. Her body was found about six weeks later, buried near the Garden State Parkway in Aberdeen.

When he entered his plea Tuesday, Prior-Ramirez admitted he strangled Beltran-Gomez during an argument. An autopsy found she died from homicidal asphyxia.

The couple was married for three years and had two young sons.
