Circumstances of Disappearance
Lyng was last seen after leaving a neighbors house to meet a carpet installer at her home in Palatine, Illinois on October 25, 1977.

Later that day her 15 year old daughter reported her missing. Stephanie's car was found 4 days later abandoned at O'Hare Airport. A small amount of blood in the car was determined at that time to be the same blood type as Stephanie's.

Stephanie had recently filed for divorce from her husband, Edward Lyng. Mr. Lyng was arrested in 1992 and charged with the murder of his wife. He was convicted in 1994 but has never told investigators where her body is located.

Mr. Lyng was admitted to the hospital for kidney surgery the day after his wife's disappearance.

Trial testimony indicated that Lyng planned his wife's murder and had dug her grave several days prior to her disappearance. Lyng's girlfriend at the time testified that she helped place Stephanie's car at O'Hare Airport. She also testified that Lyng told her he ambushed her, murdered her and then buried her. She stated that he returned to the grave site at a later time and mutilated her body so that, if found, it would not be identified.

One of Ed Lyng's nephews that Lyng had offered him $50,000 to kill Stephanie.

She is believed to be buried in Lake County Illinois.

Lyng is now at Menard Correctional Center and will not be eligible for release until September 2026, when he'll be nearly 92
