The "iron-clad alibi" of a former police officer arrested in the 1957 murder of a young Illinois girl is based largely on whether military personnel records from the time demonstrate that he was out of town when she vanished.
But it's not clear those records still exist.
Jack Daniel McCullough, 71, told The Associated Press in a jailhouse interview Thursday night that he had nothing to do with the death of 7-year-old Maria Ridulph, and he wants her killer brought to justice. Her disappearance terrified the small farming town of Sycamore, about 50 miles west of Chicago, and drew the personal interest of then-FBI Director J. Edgar Hoover.
He stuck to the same alibi he gave when first questioned by investigators more than half a century ago, when he was 18: that he could not have committed the murder because he had traveled to Chicago that day for military medical exams before enlisting in the Air Force.
McCullough said he didn't believe investigators had ever tried to verify that he was in Chicago that day for medical tests — and records of those tests should still exist in his file at the National Archives repository of military personnel records in St. Louis, he said.
"St. Louis will have records of everything," he said. "If somebody would go there, it would exonerate me."
A fire at the archives in 1973 destroyed millions of military personnel records — including about 75 percent of records of Air Force personnel discharged between 1947 and 1964 whose last names came alphabetically after H. McCullough left the Air Force in 1960.
A clerk at the repository told The Associated Press Friday that no records could be made public without McCullough's signed permission, and there was no immediate way to determine whether his records were among those destroyed. Officials would have to hunt through boxes of paper files to see if his was there.
"I have an iron-clad alibi," McCullough insisted. "I did not commit a murder."
McCullough was arrested in Seattle last week after investigators said new evidence — including one record that does exist — undermined his alibi. He's being held in the King County Jail on a fugitive charge pending his return to Illinois.
According to a police affidavit in the case, last year, McCullough's high school girlfriend discovered his train ticket to Chicago behind a framed photograph of them — and it was unused.
Detectives wrote that when he was questioned in 1957, he claimed he had traveled to Chicago by train.
McCullough maintained that he doesn't know how his high school sweetheart wound up with the unused train ticket — but learning of its curious discovery behind the photograph tickled him. The couple broke up when he left to join the Air Force.
"She doesn't know it, but I loved her for decades," he said. "She got married, and I put it aside and said, 'Eh, give up.'
"But she keeps a picture of me and her for 50 years. Imagine that."
Though Sigman said she was never asked to identify McCullough as the suspect at the time, she picked his photo out of a montage detectives showed her last September, the affidavit said.
The affidavit also alleged that McCullough has a history of molesting girls.
One young witness told agents in 1957 that he had sexually abused her on numerous occasions, and in the early 1980s he lost his job with the Milton police department in Washington state after he was accused of sexually abusing a runaway in her early teens. He pleaded guilty in 1983 to unlawfully communicating with a minor.
McCullough declined to discuss those topics with the AP.
"Don't go there. What I did or didn't do in my private life that would make me look bad, so what?" he said. "I didn't commit a murder, and that's all I'm charged with."
McCullough said he didn't remember everything he told the FBI in 1957, but he said there's a good reason his train ticket was unused: He never used it.
He says his stepfather gave him a ride to Chicago, and after a long day of physical and psychological tests, he hitched a ride with someone he'd just met to Rockford. From Rockford, a drive of more than 40 miles from Sycamore, he called home to ask his stepfather to come pick him up.
Investigators wrote in the affidavit that they have verified that a collect call was made from a Rockford pay phone to McCullough's childhood home that night, lasting from 6:57 to 6:59 p.m. If he made that call, he said, "How am I involved in a kidnapping at 6 p.m. in Sycamore?
A fifth-grader can figure this out."
Rockford is roughly on the way from Sycamore to where the girl's body was eventually discovered, in far northwestern Illinois.
