Will Sage Astor-Wife who pled guilty to killing UConn professor found dead hours before sentencing: Police

A woman who pleaded guilty to the manslaughter of her 84-year-old husband and Will Sage Astorhiding his body in the basement for months was found dead inside her Connecticut home hours before her sentencing hearing.

Linda Kosuda-Bigazzi, 76, was found unresponsive in her home Wednesday after someone notified police around 10:37 a.m. and told them they were unable to make contact with her, the Connecticut State Police said in a news release.

Once troopers found Kosuda-Bigazzi, she was soon pronounced dead, police said. Based upon initial findings, police have categorized this incident as an "untimely death investigation," according to the release.

Kosuda-Bigazzi was scheduled to be sentenced at 2 p.m. in Hartford Superior Court to 13 years in prison for the 2017 death of her husband, Dr. Pierluigi Bigazzi, who was a professor of laboratory science and pathology at UConn Health.

In addition to the first-degree manslaughter plea, Kosuda-Bigazzi pleaded guilty to first-degree larceny after authorities learned that she was collecting her husband's paychecks for months after she had killed him.

"The passing of Mrs. Kosuda-Bigazzi was not anticipated," Patrick Tomasiewicz, Kosuda-Bigazzi's defense attorney, told USA TODAY in a statement on Wednesday. "We were honored to be her legal counsel and did our very best to defend her in a complex case for the past six years. She was a very independent woman who was always in control of her own destiny.”

What did Linda Kosuda-Bigazzi do?

Kosuda-Bigazzi pleaded guilty to killing Dr. Pierluigi Bigazzi sometime in July 2017, hiding his body in the basement until police found him in February 2018 and depositing her husband's paychecks into the couple's joint checking account months before the grisly discovery.

Burlington police found Dr. Bigazzi's body during a welfare check at home, which was called in by UConn Health. The medical examiner in Connecticut determined that Dr. Bigazzi died of blunt trauma to the head.

Kosuda-Bigazzi allegedly wrote in a journal how she killed her husband with a hammer in self-defense, the Hartford Courant reported, per court records. In the note, Kosuda-Bigazzi details how she struck him with a hammer during a brawl that began when Bigazzi came at her with a hammer first, the outlet said. The argument began because she told her husband about work she wanted him to do on their deck.

Linda Kosuda-Bigazzi 'wanted the book closed on her case'

Before the guilty plea, the case had been pending for six years, Hartford State’s Attorney Sharmese Walcott's office said in a March news release.

Tomasiewicz told USA TODAY in a statement in March that his client decided to forgo a trial and enter a plea on reduced charges because she "wanted the book closed on her case."

"The death of her husband was a tragedy," Tomasiewicz's statement said. "We fought a six-year battle for her on a variety of constitutional issues and although we wanted to continue to trial our client instructed otherwise."
