HONOLULU -- An Army medic has pleaded not guilty to charges he conspired with his lover to kill his wife in their Honolulu home and make it look like a burglary.
The FBI arrested Sgt. Michael Walker on Wednesday, after a federal grand jury indicted him for murder in last year's stabbing death of his wife, Catherine Walker. She was found dead last November in the home she shared with her husband at Aliamanu Military Reservation.
The indictment includes excerpts from text messages and emails he allegedly sent to Ailsa Jackson about his desire to get rid of his wife.
"I want you so bad!!!" was one text message on Oct. 12, 2014. "If only someone was out of the way!"
In a November email, Jackson allegedly wrote about needing Walker's permission to act: "The anticipation is exhausting. The thrill is faltering. I'm growing impatience (sic), tired and hungry for action."
He allegedly responded, "The sooner the better."
Prosecutors say the two discussed carrying out the killing on Nov. 14, 2014, when Michael Walker would be at work. Around midnight, Jackson allegedly entered the home with a key left near the back door, grabbed a knife from the kitchen and stabbed Catherine Walker multiple times in the upstairs bedroom where she slept.
Jackson was indicted in April. She was arrested in Indiana and extradited to Honolulu. She has also pleaded not guilty.
Walker couldn't be reached for comment while in FBI custody. He is a health care specialist who has been assigned to Tripler Army Medical Center since 2013, said hospital spokesman Jim Guzior. He has been deployed once to Afghanistan and twice to Iraq, Guzior said.
