A North Carolina man has admitted to murdering his industrial engineer wife — and staging her death to look like a suicide.

Michael Aaron Matthews, 42, was sentenced Monday to 13 years to 16 years and nine months in prison after pleading guilty to second-degree murder in the death of Nabaruna Karmaker, 33. She was found shot to death in the couple’s home in Morrisville, a town some 15 miles northwest of Raleigh.

Her arm was around a box that contained the ashes of her recently deceased dog, Boomer. A potted plant was also next to her arm, and a gas can and the 12-gauge shotgun were nearby.

Matthews had called first responders to the home, claiming there had been a “double suicide.”

But the details of his story didn’t add up.

Karmaker’s two shotgun wounds, one to her torso and the other to her neck, were fired in “quick succession” from different ranges, the prosecution said, according to a report from The News & Observer. The autopsy reportedly stated suicide was “highly unlikely” in light of that.

Karmakar, an industrial engineer, researcher, and data scientist, had reportedly filed to divorce Matthews a week before.

“You took advantage of her ability to love and her kind soul,” Karmakar’s sister, Monita Karmakar, said in a statement read in court by Assistant District Attorney Christina Koscianski. “When she wanted to leave you, instead of letting her go, you decided to end her life so no one else could feel her love.”
