The loss of a Connecticut lady who had committed herself occurred only a few hours before she was supposed to be sentenced in connection with the loss of her husband.

On Monday, August 12, the Connecticut Office of the Chief Medical Examiner verified to PEOPLE that Linda Kosuda-Bigazzi, who was 76 years old and was discovered de.ad at her home in Burlington on the morning of Wednesday, July 24, had committed suicide. A toxic reaction to ethylene glycol was determined to be the cause of her loss by the medical examiner’s office.

According to the Centers for Disease Control and Prevention (CDC), ethylene glycol is a “industrial compound” that may be found in a variety of consumer goods, including but not limited to “antifreeze, hydraulic brake fluids, some stamp pad inks, ballpoint pens, solvents, paints, plastics, films, and cosmetics.”

At around 10:37 a.m. on July 24, the Connecticut State Police were sent to the residence of Kosuda-Bigazzi after receiving a complaint from a person stating that they were “unable to make contact with the resident.” It was reported by the Associated Press that she was set to be sentenced for the killing of her husband, Dr. Pierluigi Bigazzi, who was 84 years old, at two o’clock that day.

“Attempts by responding Troopers to initiate contact with anyone inside of the residence were unsuccessful and with the assistance of the local fire department, Troopers made entry into the residence,” according to information provided by the Connecticut State Police. “An unresponsive female was located within the residence, who was subsequently pronounced deceased at the scene.”

Kosuda-Bigazzi was discovered de.ad four months after she entered a guilty plea to a charge of manslaughter in the first degree and theft in the first degree at a court hearing in March. The first degree charges were brought against her.

On February 5, 2018, her husband, who worked at the University of Connecticut, was discovered de.ad in their basement, according to a criminal information summary that was previously acquired by PEOPLE. This led to her arrest.

Sharmese L. Walcott, the State’s Attorney for the Hartford Judicial District, issued a news statement in which she said that the police were asked to do a welfare check at the residence “from the victim’s employer, who had not heard from the victim for several months.”

“An investigation showed paychecks from the victim’s employer continued to be deposited into the couple’s joint checking account from the time of his loss, which authorities believe to be sometime in July 2017, until his body was discovered in early February 2018,” according to the statement issued by authorities.
