An Infant Disappeared in 1982 and Was Never Seen Again. Decades Later, Her Father Was Convicted of Her Murder

Isiah Williams took his daughter, Olisa, from his mother's arms during an altercation

The father of an infant girl who was last seen in Ann Arbor, Mich., in 1982 was convicted of her murder after four decades.

Isiah Williams, 78, of Chicago, was found guilty of first-degree murder in the presumed death of his 8-month-old daughter, Olisa, the Michigan Department of Attorney General said in a press release.

The attorney general’s office said Williams took Olisa from her mother’s arms in Ohio during an altercation in April 1982. He then took the baby to Michigan, according to the release.

Olisa was never found and has since been presumed dead, prosecutors said.

Authorities alleged Williams had a history of domestic violence against Olisa’s mother, who continued to search for her daughter for decades.

In 2021, the Ann Arbor police department referred the case to the attorney general after completing new interviews. Williams was charged with murder that year.
