As his mental health had deteriorated over the years, so now did his physical health; in October 1993, Kiszko was diagnosed as suffering from angina. He died at 1:00a.m. on 23December that year, after suffering a massive heart attack at his home, 18 years and two days after he made the confession that helped lead to wrongful conviction for murder. Molseed's sister was one of those who attended his funeral, two weeks later, on 5 January 1994. Four months after her son's death, Charlotte Hedwig Kiszko, died at Birch Hill Hospital, Rochdale, on 3 May, at the age of 70. The two are buried together in Rochdale Cemetery.
