A Yale professor has broken her silence following the arrest of her 81-year-old father, who has been implicated in the 1982 murder of her mother. This case had remained unresolved for over 40 years.

The Foster City Police Department in California announced on November 24 that Patrick Galvani was apprehended in San Francisco and subsequently detained at the San Mateo County Jail. He faces a murder charge in connection with the death of his wife, Nancy Galvani.

Alison Galvani, a Yale epidemiology professor, was just about five years old when her mother’s life was tragically taken. In a December 3 interview with the Los Angeles Times, she expressed her gratitude to the investigators and prosecutors for their dedication to “pursuing justice for my mom.”

“Their extraordinary blend of compassion and determination is driving their relentless efforts to bring clarity to even the most shadowed cases,” she conveyed in a message to the publication.

The arrest of Patrick Galvani by the Foster City Police Department marks a significant development in the cold case concerning the 1982 murder of Nancy Galvani.

Nancy’s body was found in August 1982 “floating inside a sleeping bag near the San Mateo Bridge” in Foster City, police said. Although the case was reviewed several times over the years, authorities said it “remained unsolved until recent developments allowed investigators to move forward.” Officials did not specify what those developments were.

Patrick had been considered a suspect early in the investigation, the L.A. Times reported, but charges were dropped due to a lack of witnesses and usable evidence. His attorney at the time said he had passed a polygraph test, and Patrick said in court filings that his wife was experiencing a “mental illness.”

Following Patrick’s arrest, his current attorney, Douglas Horngrad, told the L.A. Times that his client is innocent.

“This murder charge was filed against him years ago and the case was dismissed for lack of evidence,” Horngrad said. “As I understand it, the evidence is the same, and we believe the outcome will be the same. Mr. Galvani will be exonerated again.”

Prosecutors expressed a different view. 

San Mateo County District Attorney Stephen Wagstaffe told the L.A. Times, “We think we have enough to convict and we have an ambitious prosecutor who can accomplish that.”

At the time of Nancy’s death, she and Patrick were separated. She had filed for divorce, secured a restraining order, and moved out of their Pacific Heights home to a residential hotel in San Francisco, according to the L.A. Times.

On Aug. 8, 1982, Patrick allegedly asked Nancy to pick up their daughter Alison a day earlier than scheduled under their shared-custody arrangement. Nancy disappeared that evening, and her body was later discovered. Her yellow Buick was found inside Patrick’s garage.

Alison told the L.A. Times that she had long feared “my father used me as bait to lure my mother to her death.” The uncertainty surrounding her mother’s final hours, she said, has haunted her for decades, even overshadowing her wedding day, when she asked her father to walk ahead of her so she did not “have to touch him.”

She also recalled confronting him during a 2008 visit to her home in Connecticut, telling him, “You killed my mother.” According to Alison, he replied, “It wasn’t my fault.”

According to jail records, Patrick Galvani is being held without bail. His next court appearance is scheduled for Jan. 15.

Alison Galvani, Horngrad’s office and the San Mateo County District Attorney’s Office did not respond to requests for comment.
