A man killed when he was struck by an automobile on the H-2 freeway Monday night has been identified as Army Spc. David Jernigan, 22.

A native of Zephyrhills, Fla., Jernigan was assigned to the 70th Engineer Company, 65th Engineer Battalion, 130th Engineer Brigade, 8th Theater Sustainment Command, based at Schofield Barracks, said Lt. Col. Matthew Garner, public affairs officer for the 8th Theater Sustainment Command.

Police said Jernigan, who was living in Wahiawa, hit the median barrier while going townbound on H-2 freeway about a quarter-mile north of Kamehameha Highway onramp at 10:50 p.m. Monday.

He stopped his vehicle and then jumped into the Wahiawa-bound lanes where he was hit by a 2007 Volkswagen Jetta driven by a Mililani woman, 25. The woman suffered minor injuries and was treated at Wahiawa General Hospital.

Police said it is unclear why Jernigan tried to cross the freeway on foot but believe he had been drinking.

The incident is being investigated jointly by the police and the Army.

Jernigan had been in the Army for three years, Garner said. He deployed to Iraq from 2008 to 2009. He was awarded the Army Commendation Medal, the Army Good Conduct Medal, the National Defense Service Medal, the Iraqi Campaign Medal with Campaign Star, the Global War on Terrorism Service Medal, and the Army Service Ribbon.
