A Neptune Township 21-year-old risks spending nearly as much time in prison as he's lived so far, if convicted and sentenced for attempted murder related to a shooting there last St. Patrick's Day.

Omar Jackson was charged Monday night and incarcerated at $650,000 bail, according to information from the office of acting Monmouth County Prosecutor Chris Grammiccioni.

He was given no option for release on payment of 10 percent, and a bail source hearing precedes release. Jackson's also been ordered to refrain from contact with the victim.

Sean O'Rourke, 19, of Asbury Park, survived the shooting that caught police attention just after 8 PM March 17 on Myrtle Avenue.

O'Rourke's single back wound was considered life-threatening and required treatment at Jersey Shore University Medical Center in Neptune, officials said.

The penalty for an attempted murder conviction is up to 20 years behind bars. Jackson would be required to serve 17 years under New Jersey's No Early Release Act.

He also faces two second-degree weapons counts, each with a maximum sentence of 10 years and parole eligibility after five under terms of the Graves Act, authorities said.
