Doris Hammack of Detroit, Michigan, came to Yoknapatawpha County claiming to be LeAnne Izard, who hadn't been seen since the murder of her parents 40 years earlier.
On April 11, 1958, the bodies of Richard and Lisa Izard were found outside their Yoknapatawpha County home.
Then Detective McPhail and a deputy went around to all the neighbors to find out what they'd seen and heard that day. They started with next-door neighbor Lydia Catlett and then spoke to Roland Bland.
Before going home to get a few hours of sleep, the investigators added their notes to the case file.
By morning, the press had assembled a report on the murders for the newsreels.
During the investigation, the sheriff's department interviewed hundreds of people in Yoknaptawpha to get more information about the Izards.
All of the prime suspects were among the Bowlan Glove employees who were laid off the day Richard and Lisa were killed.
The sheriff's department talked to the bartender at Sid's to see if his story matched up with what they'd been hearing from the laid-off men, and they also interviewed a number of other potential suspects who were eventually cleared of any involvement in the Izard murders and the children's disappearance.
While Deputy Kuhn went to Memphis to check out Elliot Perch's alibi, other investigators went through the Bowlan Glove Factory personnel files, focusing on top suspects like Jessie Danahy, Howard Hadley, Walter Hinkley, and Elbert Warren.
Finally, as they ran out of leads to pursue, they reviewed the information they had collected on the potential suspects.
Eventually, the case went cold. Two years later, the local newspaper reported on the status.
Doris Hammack went to the sheriff's department to talk to a detective about her possible connection to the Izard case.
When Detective Nelson learned that Detective McPhail's prime suspect was in a nursing home, he talked to the man's son and daughter-in-law first to find out whether he was well enough for an interview.
At a local nursing home, Detective Nelson met with Elbert Warren to find out what he remembered about the case.
Then he went to see Frank Abbott to get his take on the time of the Bowlan Glove layoffs and the Izard murders.
Later, Doris showed Detective Nelson an anonymous letter she received at her hotel.
Later, Detective Nelson went to see a man mentioned in the papers to see if he could fill in any of the holes in the story.
Finally, the local newspaper gave the community as much of a solution to the Izard mystery as they were ever likely to get.
