Ex-Army medic, his mistress sentenced in brutal 2014 murder of his wife
HONOLULU, Hawaii (HawaiiNewsNow) - A former Army medic and self-proclaimed “sex addict” who pleaded guilty in the love triangle murder of his wife was sentenced to 35 years behind bars on Monday.
Michael Walker, 40, had been charged with first-degree murder in the death of his wife, Catherine, in 2014. To avoid a life sentence, he pleaded guilty to second-degree murder.
Michael Walker’s co-defendant, 29-year-old Ailsa “Lisa” Jackson, also pleaded guilty to murder. She was sentenced to 30 years behind bars.
Jackson said she and Walker were having an affair.
And she admitted she’d broken into the Walker home at the Aliamanu Military Reservation ― using the key Michael Walker left for her ― and stabbed Catherine Walker over and over again.
Jackson waited 30 minutes and watched Catherine Walker take her last breath before leaving.
In a November 2014 interrogation, video of which HNN obtained, Michael Walker admitted to cheating on his wife but pinned his wife’s murder on Jackson.
He also admitted to having multiple other affairs, and even taking payment from men for sex.
“I have a problem. I’m a sex addict," he said, adding that Jackson threatened his wife’s life.
Prosecutors say Walker not only knew what Jackson was planning, but encouraged her to do it.
In handing down Walker’s sentence Monday, the judge told him that while Jackson “wielded the knife that killed your wife ... you were in control.”
Jackson suffered from mental illness for years. She was not taking her medication during that time because of a lapse in her heath insurance. She had been diagnosed with Schizoaffective disorder.
In court it was revealed that during the crime, Jackson asked Catherine Walker if she forgives her and Catherine answered, ‘Yes’.
During the court proceeding, Douglas Plotz, Catherine’s father also told the court that he forgives the two if them.
Longtime friend of Catherine Walker said loved ones are satisfied with the judge’s sentences, “We got something. They’re not walking free. And then after this life, they have to answer to the lord for their souls,” said Shay, who didn’t want her last name used.
Walker and Jackson met through an online dating site in September 2014.
Walker told her that he was married and that his “deepest desire” was to have his wife gone, but he couldn’t divorce her, Assistant U.S. Attorney Tom Brady said during a plea hearing for Jackson.
The lovers then discussed Jackson carrying out the killing while Walker was at work so he would have an alibi, Brady said.
Walker has been behind bars since 2014.
And in 2017, he was sentenced to 10 years behind bars for sexually abusing a child, assault and communicating a threat after authorities investigating his wife’s murder found child pornography. He was also convicted of prostitution after investigators found social media sites where he was selling himself to men for sex.
