A 79-year-old woman has been charged with the murder of her stepfather, whose remains were discovered in the Arizona desert 50 years ago. She is also accused of living in his home and collecting his retirement benefits during that time.
Arrest and Charges
Carol Ann Beall was arrested on Thursday, May 28, in connection with the death of William Reginald Sipfle. She was charged with first-degree murder by the Pima County Sheriff’s Department. Beall has never been arrested before and is being held on a $500,000 bond.
The Cold Case
Sipfle went missing at age 73, but no police report was filed by his family. For five decades, the family had no answers about his disappearance. In October 1975, human remains were found at a waste transfer station in Pima County, but authorities were unable to identify them at the time due to technological limitations.
Breakthrough Through Genealogy
Advances in genealogy forensics allowed investigators to make a connection between the remains and Sipfle’s family in late 2025. A third-party lab helped link the remains to distant relatives, eventually confirming the identity of Sipfle. This breakthrough provided closure for his family and reopened the investigation into his disappearance.
Beall’s Involvement
Investigators focused on Beall when they learned she worked at a museum near the area where the remains were found. Beall, a retired U.S. Postal Service employee, has been living in Sipfle’s home for over 50 years.
Prosecutors allege she used between $250,000 and $600,000 from his pension and Social Security benefits. The state claimed that this income was a primary source of her wealth following her stepfather’s death.
Ongoing Investigation
The investigation into Sipfle’s death is ongoing. Authorities hope it will uncover additional details about the circumstances surrounding the murder. The sheriff noted that while not all answers may be found, modern forensic science has helped confirm the identity of Sipfle and may shed light on what happened.
Family Reaction
Sipfle’s family expressed relief at finally learning the fate of their grandfather. They are now processing the circumstances of his death and reflecting on the decades of uncertainty following his disappearance. The family appreciates the closure provided by the identification of his remains and continues to hope for further answers as the investigation continues.
