New technology is helping Stamford police make progress on a murder investigation that is more than 20 years old.

In December of 1990, Marie Joseph, a 20-year-old woman with two young daughters and plans to go to design school, was reported missing by her husband.

Joseph's sister Geraldine and the rest of her family immediately suspected there was more to the story.

In August of 1991, Stamford police were called to 45 Research Drive where a skull and three vertebrae were found. They say they could not link the remains to the missing woman.

Officials say the two cases were left unanswered until four years ago, when officer Wayne Macuirzynski pulled the skull out of evidence and sent it to the state forensic lab where new technology extracted a useful DNA match to Joseph.

Investigators say they are still looking for answers to solve the murder. Anyone with information is asked to call the Special Victim's Unit at 203-977-5884.
