On the night of Tuesday, January 3, 1978, Michelle Franklin, 22, and her husband John Franklin, Sr., 35, were shot to death inside their Eddyville, Iowa, home. The couple were killed sometime between 10 p.m. and midnight; Michelle’s mother discovered their bodies the following day.

Investigators quickly focused on John Franklin Jr., the 14-year-old son of John Sr. from a previous marriage. He was picked up the morning after the murders as a runaway and was charged after reportedly admitting to the killings. At trial, however, Franklin Jr. was acquitted of all charges.

With the primary suspect found not guilty and no subsequent leads reported, the case went cold and remains unsolved. Does anyone from Eddyville in 1978 remember details that could shed light on what happened that night?
