Cautiously Optimistic: Inside the 2026 Billy Mansfield Digs in Hernando County

In late June 2026, residents along Sunshine Grove Road in Brooksville watched a multi-agency operation move onto a ranch property. The Hernando County Sheriff’s Office, the FBI, the State Attorney’s Office, and forensic investigators from Florida Gulf Coast University were searching for additional victims of convicted serial killer Billy Mansfield Jr., forty-five years after four women were found buried on his family’s property.

Sheriff Al Nienhuis said his office was cautiously optimistic about finding something, while also noting that they were dealing with a serial killer who is less than truthful and who may be mistaken given how much time has passed.

By roughly 3:30 that Tuesday afternoon, the search was over. No remains were located. The sheriff’s office said it has no further excavations planned in connection with the investigation.

William Mansfield Jr. was born in 1956 in Grand Rapids, Michigan, the oldest of five children. His father, William Sr., was a convicted child molester who reporting says served ten years for lewd acts against young girls and had served sentences in both Michigan and Nevada. The family later lived on a wooded, junk-strewn six-acre property on Centerwood Avenue in the Weeki Wachee Acres area of what is now Spring Hill, off US 19.

Mansfield had a record before 1980. In 1977 he pleaded guilty to a sexual misconduct charge in Michigan and received six months, a sentence eased after he testified against his cellmate. He returned to prison shortly afterward for assaulting two teenagers and violating parole. At the time of his arrest for murder he was twenty-five and working as an electrician.

In the late 1970s Billy and his brother Gary traveled west, and by 1980 Billy was reportedly working at a mushroom farm in Santa Cruz. On December 6, 1980, Rene Abbey Saling, a twenty-nine-year-old mother of three from Watsonville, California, was raped and strangled. Mansfield was charged and later convicted.

The brothers were arrested in Nevada in 1980. Gary Mansfield’s accessory charges were dropped after he agreed to cooperate. Information developed in that California investigation, along with anonymous tips including one naming a woman missing for nearly a year, sent Hernando County investigators back to the family property with a search warrant in March 1981.

In March 1981, while the national news cycle was consumed by the attempt on President Reagan’s life, a short item in the New York Times described an ongoing search for the remains of several women in the junkyard surrounding a family’s mobile home in Weeki Wachee Acres, Florida. By that point deputies had recovered the skeletons of two women and the partial skeleton of a third. Officers from Tampa and metal-detecting specialists assisted.

Four women were ultimately recovered from that ground. Mansfield later told a court that he buried them close to the house because he wanted them near him.

During the same period, his father was arrested for the rape of five children between the ages of five and ten. According to court documents and prosecutors cited in local reporting, Mansfield brought abducted women back to the property and presented them to his father and brother while they were still alive. That account describes a household rather than a lone offender, and only one member of that household is serving life for murder.

The victims

Elaine Louise Ziegler, 15, of Warren, Ohio. She went missing from a KOA campground near Brooksville while vacationing in Florida with her stepfamily.

Sandra Jean Graham, 21, a Tampa native, a divorcee, and an employee of Hillsborough Community College. She was last seen leaving a Tampa bar in late April 1980. Accounts differ on whether the date was April 26 or April 27.

Theresa Fillingim. Her remains were recovered from the Mansfield property in the early 1980s, and her identification came later than the first two. Her name is frequently omitted from national coverage, which tends to describe her only as one of “two others.”

The fourth woman remains unidentified. She has a registered DNA profile, and genealogists are working to trace distant relatives. That work is the most active thread in the case today.

Rene Abbey Saling, 29, of Watsonville, California, killed December 6, 1980.

Carol Ann Barrett, 18, of Zanesville, Ohio.

The prosecution did not proceed smoothly. Mansfield’s first prosecution ended in a mistrial in August 1981, with jurors split nine to three in favor of conviction. That same year he was caught attempting to escape from prison with a fellow inmate, Ben Barrigan.

In 1982 he pleaded guilty to the Florida murders rather than face a death sentence, along with an attempted sexual battery charge involving a fifth female victim. He received four life sentences in Florida on top of his California sentence, and is housed at the California Health Care Facility in Stockton.

During those original proceedings, Mansfield hinted that more bodies were hidden across west-central Florida. Sheriff Nienhuis has said Mansfield indicated during the 1982 trial that there might be more. Every excavation since traces back to that claim.

Carol Ann Barrett was eighteen when she traveled from Zanesville, Ohio to Daytona Beach on spring break with high school friends. At around 2 a.m. on March 23, 1980, she was abducted from the Treasure Island Motel in Daytona Beach Shores, a building since demolished. Her body was found the following day more than a hundred miles north, in a ditch along Interstate 95 near Pecan Park Road in Jacksonville. Her death was ruled a homicide, and a police sketch was created from interviews with the friends who had been in the motel room.

The Jacksonville Sheriff’s Office cold case unit reopened the case in August 2017 and developed Mansfield as a person of interest in 2020. In September 2022, after multiple interviews spanning two years, Mansfield stated that he was the man in the police sketch, then confessed to the abduction and the murder. The announcement was made public in January 2024. The State Attorney’s Office in the Fourth Judicial Circuit declined to prosecute, citing the life sentences he is already serving.

The geography matters: Daytona Beach is on the Atlantic coast and Jacksonville is at the top of the state, far from a property off US 19. Mansfield’s movements were never confined to Hernando County.

On October 27, 2020, Gary Mansfield was arrested on drug charges at the Centerwood Avenue property, where he and his father were still living. Detectives said they found items unrelated to the drug investigation. The following morning, investigators returned with heavy equipment, forensic anthropologists, and a University of South Florida forensics team, working alongside the medical examiner’s office from sun-up to sundown. By that evening, the reporting was that human remains had been found in the yard.

That discovery has never been publicly resolved into a named victim. When investigators laid out the Hernando County count again in 2026, they described four bodies recovered decades earlier, three identified as Ziegler, Graham, and Fillingim, and one still unknown.

Nienhuis has said Mansfield indicated there could be more bodies in Hernando, Pasco, and Pinellas counties, but that investigators were unable to reach an agreement that would have provided additional information in exchange for reduced charges.

The sheriff’s office reopened portions of the investigation roughly three years ago, reviewing thousands of case files and interviewing Mansfield with federal and state assistance. An earlier excavation at another location identified during that review turned up no human remains. Continued record review pushed investigators north and west of the earlier search areas. Officials have said they do not know whether Mansfield’s claims about Pasco and Pinellas are accurate.

On Monday June 22, 2026, archaeological cadaver dogs, trained to detect decades-old remains rather than recent ones, worked an area near Fort Dade Avenue and Citrus Way and found no indication of buried human remains. The teams then moved to the Dry Creek Ranch and Sunshine Grove Road area, where the dogs gave light hits, enough to justify excavation.

On Tuesday, June 23, 2026, the excavation went forward. State Attorney Bill Gladson said that if there are additional people there could be several, or there could be none, and that if there are bodies out there, they want to give them a proper burial and get families the answers about what happened to their loved ones.

Nothing was found. There is precedent for that outcome: UPI reported in April 1981 that an informant’s information had left detectives certain they would find at least two more bodies on the property, and that belief never bore out.

Bill Mansfield III, Billy Mansfield’s son, now lives in Michigan. He has spoken publicly about the cost of sharing his father’s name, saying people automatically assume that is you, too. He has said he believes his father is innocent and pleaded guilty only to avoid the death penalty, and has wondered whether new evidence could point to a different suspect.

He has also said he believes more bodies will be found on the family property, telling WFLA that he cannot see someone stopping at one, and asking why, if his uncle knew where remains were, those families did not get their people back forty years ago.

Both statements deserve reporting. The strongest counterweights to the innocence claim are the Barrett confession, given voluntarily in September 2022 by a man already serving five life sentences about a sketch drawn in 1980 from the accounts of teenagers who had been in the room, and Mansfield’s own statement in open court that he buried the Hernando County victims near the house because he wanted them close.

If a family member disappeared in Hernando, Pasco, or Pinellas County in the mid to late 1970s or in 1980 and was never accounted for, contact the Hernando County Sheriff’s Office cold case unit. With genetic genealogy work underway on the remaining unidentified victim, family reference DNA and consumer testing matter more in this case right now than they ever have.
