Walker family murders
1959 murder case
Authorities believe that 24-year-old Christine Walker arrived at the family's farm home around 4pm on Saturday, December 19, 1959 and was raped and murdered by gunshot.  Her husband Cliff, 25, then arrived with their three year old son Jimmie and one year old daughter Debbie. Cliff was ambushed by gunshot. Jimmie and Debbie were then murdered. Jimmie was shot and Debbie, too, was shot in addition to being reportedly drowned in the bathtub. The actual cause of death is unknown and she could have been shot in the bathtub.  News stories noted there were gifts around the Christmas tree.
A serial killer named Emmett Monroe Spencer subsequently confessed to the murders, but the confession was discredited by Sarasota County Sheriff Ross Boyer, who labeled Spencer a pathological liar. Spencer’s confession was "determined to be cleverly constructed from real murders written up in newspapers and true-crime novels that he liked to read." In 1994, a female bartender in Stroudsburg claimed that one of her customers had boasted of killing the Walker family; this tip was never verified.
Police never identified a motive, and 587 people were suspects at one time or another. The case remains open.
In 2012, the Sarasota County Sheriff's Office began investigating possible links between the Walker family murders and Perry Smith and Richard "Dick" Hickock, who had been convicted and executed for the 1959 murders of the Clutter family in Holcomb, Kansas. The Clutter murders were the topic of Truman Capote's 1965 best-selling true crime book In Cold Blood. While that book devoted several pages to the Walker case, it dismissed a possible connection to Hickock and Smith, asserting that the two men had an alibi for that day. However, records and witness accounts collected by Kansas and Florida investigators show several factual contradictions in Capote’s account.
The Sheriff's Office admitted that Hickock and Smith had been considered suspects as far back as 1960. After killing four members of the Clutter family in Kansas, 34 days before the Walker murders, Smith and Hickock fled to Florida in a stolen car, and were spotted at least a dozen times between Tallahassee and Miami. The pair checked into a Miami Beach motel, about four hours from Osprey, and checked out on the morning of the Walker murders. At some point that day, Smith and Hickock bought items at a Sarasota department store, just a few miles from the Walker home. One witness said that the taller of the two men "had a scratched-up face." The pair were arrested for the Clutter murders in Las Vegas, Nevada, on December 30, 1959, and were executed by hanging on April 14, 1965. While a polygraph test appeared to clear them of the Walker murders, at least one expert has asserted that polygraph machines of the early 1960s were notoriously inaccurate.
According to Sheriff’s records, the Walkers had been considering buying a 1956 Chevrolet Bel Air, the same kind of stolen car that Smith and Hickock were driving through Florida. It is therefore believed that Smith and Hickock may have gained entry to the Walker home on the pretense of selling their car.
In December 2012, Sarasota County investigators announced they were seeking an order to exhume Smith’s and Hickock’s bodies from the Leavenworth Prison graveyard, in the hopes that mitochondrial DNA extracted from their bones could be matched to semen found at the Walker home.
After a court order was obtained, Hickock's and Smith's bodies were exhumed at the Mount Muncie cemetery in Kansas on December 18, 2012. DNA was extracted and the bodies reburied that same day. Kansas authorities stated that they would process the DNA samples with active cases taking higher priority, and that results would take "weeks or months." In August 2013, the Sarasota County Sheriff's office announced they were unable to find a match between the DNA of Perry Smith or Richard Hickock with the samples in the Walker family murder. Only partial DNA could be retrieved, possibly due to degradations of the DNA samples over the decades or contamination in storage, making the outcome one of uncertainty (neither proving nor disproving the involvement of Smith and Hickock). Consequently, investigators have stated that Smith and Hickock still remain the most viable suspects. However, based on the personal items that were stolen, Katherine Ramsland, of the University of Pennsylvania, finds Smith and Hickock unlikely and instead suspects that the killer knew at least one member of the Walker family.
