In January, staff at UConn Health tried to contact Bigazzi via email and then left a voice message on his office phone about a routine administrative matter but by Feb. 5 had received no response, according to Woods. On that day, a department head at UConn Health alerted UConn police, who went to Bigazzi's Burlington home to perform a well-being check. The UConn officers got no response when they knocked on the door and were soon joined by a Burlington constable and a state trooper. ||||| A 70-year-old woman was arrested for murder after her 84-year-old husband -- a University of Connecticut Health doctor and professor -- was found dead from blunt head injuries, officials said. 
 
 On Feb. 5, police responded to a home in Burlington, Connecticut, for a well-being check on Dr. Pierluigi Bigazzi, 84, and found him dead inside, Connecticut State Police said. Bigazzi's wife, Linda Kosuda-Bigazzi, was at the home and initially did not let authorities inside, according to a statement from UConn Health. 
 
 Bigazzi's death was ruled a homicide by blunt injuries to the head, the medical examiner's office told ABC News. 
 
 On Feb. 9, Kosuda-Bigazzi, 70, turned herself into police, and was charged with murder and tampering with physical evidence, state police said. 
 
 Kosuda-Bigazzi appeared in court today but did not enter a plea. Her attorney declined to comment to ABC News. She was placed on house arrest, according to The Hartford Courant.

 While Bigazzi's body was found this month, authorities believe he may have been dead for up to eight months -- a sealed court file suggests police believe he was killed between June 13, 2017, and Feb. 5, 2018, according to the Courant. The state police declined to comment further on the case, citing the ongoing investigation. 
 
 Bigazzi was a UConn Health faculty member in the School of Medicine for over 40 years "and was an accomplished researcher and teacher in the field of pathology and laboratory medicine," UConn Health spokeswoman Lauren Woods said in a statement. 
 
 Kosuda-Bigazzi also worked at UConn Health from 1986 to 1998 as a science instructor and she then volunteering, helping her husband through the summer of 2017, Woods said.

 Bigazzi last taught in the spring of 2017, she said. 
 
 Then, in the summer of 2017, Bigazzi was assigned to update parts of the School of Medicine’s curriculum, create and update instructional materials, and develop materials for individualized learning courses, Woods said. 
 
 That work can be done "from any location, and it was acceptable for him to work remotely," Woods explained in the statement. "This is why his absence from the campus would not have been noteworthy or cause for concern."

 Bigazzi's key card was last on the UConn Health campus in August 2017, Woods said, citing access records. His annual review would have been scheduled for later this month and "at that time, he would have presented the work he had completed since the summer to the pathology department head for her review," Woods said. 
 
 In January, UConn staff tried to reach Bigazzi and never heard back, so his department alerted police who went to the home for the welfare check in February, according to the UConn statement. When police knocked on the door, Kosuda-Bigazzi initially didn't let them in, the UConn statement said. Officers later went inside and found Bigazzi's body. 
 
 State police ask anyone who had or may have had contact with Dr. Bigazzi between July 2017 and February 2018 -- including any contractors who worked at his home at that time -- to contact authorities at (860) 626-7922. ||||| UConn President Susan Herbst Wednesday ordered a review of the work arrangements for slain medical professor Pierluigi Bigazzi, whose last contact with the school was apparently last summer. 
 
 Bigazzi earned $200,000 last year at the UConn School of Medicine, but university officials have said the last time it was certain anyone at UConn saw him was May 25, 2017 at a meeting about grading related to a three-week class that ended in February 2017. 
 
 The 84-year-old professor’s body was found wrapped up in the basement of his Burlington home Friday. His wife, Linda Kosuda-Bigazzi, was arrested and charged with murder. 
 
 She is free on a $1.5 million bond. State police are investigating whether Bigazzi had been dead for months — possibly as far back as June 13, according to court documents. 
 
 “The review will examine whether relevant UConn and UConn Health policies and protocols were followed in this instance, and whether updated or new policies and protocols may be required,” Herbst said in a statement released Wednesday night. “The review will examine what the expectations of him were and what efforts were made to communicate with him.” 
 
 Bigazzi was a professor of pathology and laboratory medicine at the UConn medical school, which is part of UConn Health in Farmington, according to the school’s directory. He had been on the faculty since 1975, according to state records. 
 
 The May 25 meeting that Bigazzi attended could have been the last time anyone at the school saw him. The last email his department head got from him was dated July 7, according to UConn Health Center spokeswoman Lauren Woods. 
 
 Bigazzi’s key card was used for the last time on Aug. 23, although UConn officials acknowledge there is no way to know if it was Bigazzi who used it. 
 
 Bigazzi last taught a class from Jan. 24 to Feb. 13, 2017. Last summer, he was assigned to update parts of the school of medicine’s curriculum and to create and update a variety of instructional materials, Woods said. 
 
 His annual review was to be scheduled for later this month, Woods said, and he was expected to present the work he completed since summer to the head of the pathology department for review. 
 
 “Given the nature of his assignments, it was acceptable for Dr. Bigazzi to work remotely,” Woods said Wednesday. “However, it would be inappropriate for any regular full-time employee to be absent from campus and out of communication for a very lengthy period of time if they are not on sabbatical or some other form of official leave. Given that, the president instructed that this review take place.” 
 
 Herbst ordered the UConn Provost’s Office and Human Resources Department to review the circumstances surrounding Bigazzi’s work arrangements. 
 
 Linda Kusoda-Bigazzi appeared in court briefly this week and her case was continued to March 20. 
 
 The warrant for her arrest has been sealed. She is also charged with tampering with evidence. 
 
 Kosuda-Bigazzi must wear a GPS monitoring system affixed to her ankle. She must remain in her home unless she has to leave to buy food, for medical or legal appointments, or to get her mail.
– A 70-year-old woman has been charged with the murder of her husband, an 84-year-old University of Connecticut doctor and health professor who may have been dead inside the couple's home for up to eight months. Authorities arrived at the Burlington home to perform a wellness check on Pierluigi Bigazzi on Feb. 5 after university officials couldn't reach him, reports ABC News. The professor had been working remotely to update the School of Medicine's curriculum since last summer and was to present his work this month, says a university rep. Though his wife initially prevented officers from entering the home, they gained access Friday, noticed a foul odor, and found Bigazzi's dead body wrapped up in the basement, reports the Hartford Courant. They believe he died of blunt head trauma as early as June. It was around that time that Linda Kosuda-Bigazzi began helping her husband with his work, the university rep says, calling Bigazzi "an accomplished researcher and teacher in the field of pathology and laboratory medicine." Kosuda-Bigazzi, a former UConn science instructor, surrendered to police Friday and is now charged with murder and tampering with evidence, police say. She has yet to enter a plea but was placed on house arrest during her arraignment Tuesday, per the Courant. Police are now trying to determine when her husband died. Part of that effort involves a plan to review alimony checks sent to Bigazzi's first wife since the summer to see who signed them. Bigazzi's department head says she last received an email from him on July 7. His campus key card was last used on Aug. 23.
