911 calls released

"I'd like to report a double suicide," Matthews said on the recorded call.

When the 911 operator asked him to repeat the address, Matthews ended the call.

The operator called him back.

"You said you wanted to report a double suicide?" the operator said.

Matthews responded, "Yeah, thank you."

Matthews went silent then the operator asked, "Sir, can you still hear me?"

There was a pause, and the operator asked again, "Sir?"

Matthews eventually responded, "Yeah." He said something else that was indistinguishable.

The operator then asked, "Is there someone there right now?"

It sounds like Matthews sighed, then he ended the call.

The murder of Nabaruna Karmakar

Shortly after 9 p.m. on April 14, Morrisville police officers responded to Seagrave Place where they found a woman who had been shot.

33-year-old Nabaruna Karmakar died from two apparent gunshot wounds.

Her husband, 40-year-old Michael Aaron Matthews, has been arrested and charged with murder.

Matthews is in jail with no bond. He appeared in court on April 17.

He is being represented by Roger Smith, Jr., and Russell Babb; they did not give a statement in court. His next court date is May 8.

While walking out of the courtroom, Matthews blew a kiss to his parents in the gallery.

The motive for the murder is unknown. Police recovered a shotgun from the home and said Matthews made the call to 911.

Karmakar worked in research and development for SAS in Cary. SAS provided a statement on her death.

"We are deeply saddened by the death of Naba Karmakar," the statement read. "Naba was a beloved member of our SAS R&D family for the past four years. Our most heartfelt condolences go to Naba's family, friends and colleagues."

Karmakar is an NC State graduate. She received a Master of Industrial Engineering in 2016 and a PhD in Industrial Engineering in 2019.

Neighbors told WRAL News that they were shocked and couldn't believe the news. The couple were usually friendly, often saying hello and enjoyed traveling, according to those in the neighborhood.
