1987 cold case murder solved; DNA technology helps crack the case

DETROIT (WXYZ) - For almost 25 years the man who killed Joseph Ayres and his wife Winifred has remained a mystery.

That is until now.

Police say they've used DNA technology to track down the murderer.

It was back in 1987 when someone broke into the Ayres' condo on Detroit's northwest side. Investigators say the suspect was likely trying to rob the couple.

During the crime he stabbed and killed Joseph, 63, and Winifred, 66.

As the suspect escaped he cut himself and left a critical piece of evidence behind. Blood.

Detroit police saved that blood in an evidence lock-up and now because of DNA technology they were able to track the alleged killer. Detectives say Rodriguez Rayford, now 51, who was already in prison on other crimes, is the killer.

His DNA was already on file because of his convictions on previous felonies.

He'll now stand trial on two counts of first-degree murder.
