NEWTON, Iowa (AP) - An Iowa woman was charged Monday in the 1983 slayings of her estranged husband and his girlfriend, who were found bludgeoned to death at a horse ranch.
Theresa Lynn Supino’s arrest in the March 3, 1983, deaths of Steven Fisher and Melisa Gregory came on the 31st anniversary of the killings. Supino, now 53, was taken into custody at her residence in the Des Moines suburb of Altoona and charged with two counts of first-degree murder. She was being held at the Jasper County Jail in Newton on a $400,000 bond.
Supino was married to Fisher at the time of his death, but they were separated with two young kids. Fisher, 20, was dating the 17-year-old Gregory.
Fisher and Gregory’s bodies were discovered by a worker at the Copper Dollar Ranch, where Fisher worked, about four miles northwest of Newton. Autopsies found that they died of massive head injuries, and their deaths were ruled homicides.
In a written statement, Jasper County Sheriff John Halferty did not explain what led to the arrest. He said only that the development came after authorities completed hundreds of interviews and continued to process evidence.
“In the 31 years since the deaths of Steven and Melisa, the deputies, officers, agents, criminalists and many others have remained dedicated to assuring this case was never forgotten,” he said.
He said the arrest did not end the investigation, and he urged anyone with additional information to contact his office.
Court records show Supino made an initial court appearance Monday, and a preliminary hearing was scheduled for next week. She does not yet have an attorney.
The Newton Daily News reported in 2009 that Supino had announced plans to write a book about “facts, opinions and theories” related to the deaths and was soliciting residents to share information.
