SYCAMORE, Ill. (CBS) — A Seattle man charged in the kidnapping and murder of a 7-year old Sycamore girl in 1957 will be in court Wednesday to face more charges.

As WBBM Newsradio’s Lisa Fielding reports, Jack Daniel McCullough, 71, is already charged with kidnapping and murder in the death of Maria Ridulph, who was abducted from her Sycamore home in December 1957.

Her remains were found nearly five months later in rural Jo Daviess County.

On Wednesday, McCullough will appear in DeKalb County Court to be arraigned on new charges, which stem from an indictment handed down on Friday.

He is charged in the indictment with sexually assaulting a 14-year-old girl in Sycamore in the early 1960s, although it has not been specified exactly when the attack occurred.

McCullough is charged in the new case with one count of child sexual assault and four counts of indecent liberties with a child.

McCullough was arrested in Seattle in July on charges that he killed Maria Ridulph. He is being held on $3 million bond at the DeKalb County Jail.

Maria was outside playing when she vanished. A short time earlier, she had accepted a piggyback ride from a young man named Johnny; back then, McCullough used the name John Tessier.

McCullough has said he has an ironclad alibi for the murder, that he was headed to Chicago to undergo medical exams before joining the military. He used the same alibi when he was questioned about the murder at the time, then disappeared.

But one of McCullough’s former girlfriends recently found an unused train ticket hidden behind a photograph he had given her, which authorities have said shatters the alibi.

McCullough later became a police officer in Washington state.
