A woman accused of strangling her older sister to death and dumping her body in a river that runs through western New York has been found guilty of murder, according to court records. Jamie Busch was also found guilty on Tuesday, February 24, of two counts of tampering with physical evidence in connection with the death of her sister, Penny Busch, court records viewed by Us Weekly show. Prior to Jamie's trial, which lasted for about two weeks, she had pleaded not guilty to all charges, according to court records. Jamie's public defender, Nicholas Daniel Piron, did not immediately return a request for comment from Us on February 24. The case dates back to October 11, 2024, when Monroe County sheriff's deputies were asked to visit Penny's home in the Village of Honeoye Falls for a welfare check, according to an earlier news release from the Monroe County Sheriff's Office. When deputies could not find Penny on her eight-acre property, they believed her absence was "suspicious" and launched a criminal investigation, authorities said. Brian Walshe Sentenced to Life for Murdering Wife Ana Three days later, on October 14, 2024, a woman's body was discovered in an area of the Genesee River in the town of Rush, according to the sheriff's office. The body in the river was ultimately identified as Penny on October 18, 2024, the sheriff's office said. She was 62 when she died. The Genesee River, which begins in Potter County, Pennsylvania, flows north into New York and ends at Lake Ontario. Following the discovery of Penny's body, the sheriff's office said "Investigators established significant evidence and probable cause to arrest her sister, Jamie Busch, for the murder of Penny Busch." Jamie was 53 when she was arrested. A boater had initially located Penny's body in the river, according to authorities, 13WHAM-TV reported. The last sighting of Penny occurred nearly a week earlier, on October 8, 2024, according to prosecutors, who have argued that Jamie likely killed her sister between October 8, 2024, and October 14, 2024, according to the TV station. Ahead of Penny's death, prosecutors said that Jamie was renting from Penny, who was "trying to evict" her, the TV station reported. In court during Jamie's trial, prosecutors detailed internet searches Jamie allegedly made around the time of her sister's disappearance, according to WROC. Woman Arrested 5 Years After Baby's Body Was Found in Suitcase On Jamie's computer, they found queries for "How to dump body in river," "Does rain wash away fingerprints," "How to dispose of body in suitcase," as well as "How to manufacture an alibi," and "Swift flowing river near me," the TV station reported. During the search for Penny, investigators recovered three cell phones from the garbage at a Dunkin' Donuts, where Jamie is accused of dumping them, according to court documents viewed by WHEC. One of Penny's cousins, Mary Shadders, who testified in court, told the TV station and other news outlets that "We're glad that even though the jury couldn't hear the [full] story of her history that they were able to make the right decision." Jamie is due in court next for her sentencing hearing, which has been scheduled for April 23, court records show.
