“A hospital corpsman at Whidbey Island Naval Air Station was arrested Monday at the base’s main gate on suspicion that he killed his wife. Petty Officer 3rd Class Paul A. Green, 31, was arrested at about 5:45 a.m. and held by base security officials Tuesday while Naval Criminal Investigative Service detectives investigated, base spokeswoman Sarah McGruder said.The body of his wife, Linda Cynthia Roy, 29, was found in the back seat of Green’s car. Island County Coroner Robert Bishop ruled the death a homicide, listing the cause as death by asphyxiation due to strangulation. No other signs of trauma were found on the body, Bishop said. He determined the time of death as approximately 4 a.m., with a margin of error of a couple of hours either way. He said Roy was killed at her residence, 707 Sandstone Way, Apt. B., on the Seaplane Base at NAS Whidbey.Beyond a few spare details, though, base spokespeople threw tight wraps around the case.The main gate was closed after Green pulled up to the gate and turned himself in at around 5:30 a.m., base spokeswoman Sarah McGruder said. It was later reopened to traffic.According to a 911 call placed at 5:30 a.m. by NAS Whidbey firefighters, they were responding to the main gate for a man in custody who “said he killed wife one hour ago.’’ Base spokesman Howard Thomas would not confirm whether Green’s wife was with him when he pulled up to the gate. He would also not say where or how she was killed, other than the death occurred in military housing. .A base press release said Green was being “very cooperative’’ with NCIS investigators.Linda Roy was an avionics technician third class assigned to NAS Whidbey’s Aviation Intermediate Maintenance Department, according to a release from McGruder’s office. Thomas said she and Green did not have children together, but would not say whether either had children that preceded their marriage. Roy and Green were married, Bishop said, although Roy did not use his last name.Green has been in the Navy since 1993, according to a written statement from McGruder’s office. He is a corpsman assigned to the NAS Whidbey base hospital.Navy hospital corpsmen can be pharmacists, medical technicians, food service people, nurse’s aids, or physician or dental assistants. McGruder’s statement did not say which function Green performs at the hospital.Local court records show no signs of trouble in the Green’s home. District Court files show two speeding tickets on his record — both paid — but no criminal files.Green was held at NAS Whidbey Tuesday while awaiting transfer to the Navy brig in Bremerton.“The process is that an individual has been arrested, will be formally charged under the Uniform Code of Military Justice,” Thomas said. “There will be an Article 32 Hearing, similar to grand jury proceeding, and based on that, it could proceed to a court martial.””
