Authorities in Louisiana on Tuesday arrested a man who is accused of murdering his wife and her friend in 1989, according to reports.

Alexandria resident Robert Blair, 71, is facing two counts of first-degree murder in connection with the deaths of his wife, Isabelle, and her friend Marian Coutee,

The Rapides Parish Sheriff’s Office said Isabelle split with her husband in July 1989. Around that time, she got into a vehicle with Coutee and the two were never seen again. The case remained unsolved for 30 years. But two months ago, deputies received a tip that reopened the inquiry, KALB-TV reported.
