Girl’s remains found after 30 years, now family seeks killer

GREELEY, Colo. (AP) — The sister of a Colorado girl who disappeared in 1984 after a holiday concert hopes the recent discovery of her remains helps police track down who killed the 12-year-old.

Jennifer Mogensen called it a miracle that a construction crew found her sister’s remains last month. She says her family now hopes police can find the person responsible.

Jonelle Matthews was last seen on Dec. 20, 1984, entering the Greeley home where she lived with her father, mother and sister.

No one was ever arrested. Jonelle’s disappearance was among those highlighted by then-President Ronald Reagan as his administration launched a national effort to find missing children.

Police have declined to comment on the case or any potential suspects since Jonelle’s remains were found in late July.
