KANSAS CITY, Mo. – A drunken driving conviction has led to a Missouri man's arrest in a 23-year-old killing.
Prosecutors have charged 43-year-old Guy Shannon Jr., of Odessa, with first-degree murder and forcible rape after DNA evidence linked him to the crime. Prosecutors say Shannon strangled and assaulted 20-year-old Marcia Lynn Davis, of Independence, in March 1989.
Shannon became a suspect after he was convicted of driving while intoxicated in 2010 and, as a felon, had to give a DNA sample. That sample eventually tied him to Davis' killing.
She was last was seen leaving the Jackson County Jail, where she had visited a friend.
Shannon was charged Monday, although the records weren't unsealed until Thursday. No attorney for him was listed in online court records.
