Investigators have made an arrest in a cold case murder that has gone unsolved for a quarter of a century.

MassLive.com reports that Gary E. Schara has been arrested and charged with the murder of Lisa Ziegert, who was killed in 1992 in Agawam. She was 24 years old at the time of her murder.

District Attorney Anthony Gulluni announced the news of the arrest in a press conference on Monday. The suspect was reportedly arrested in Connecticut on a warrant for kidnapping, murder, and aggravated rape.

Ziegert was a teacher’s assistant who worked a second job at a card store. She disappeared after work at her part-time job in the spring of 1992. Four days later, on Easter Sunday, her body was found in a wooded area close to her place of work. A medical examiner determined that she had been raped and stabbed.

A year ago, prosecutors were able to create a composite sketch of the suspect using a new technology called DNA phototyping.

The District Attorney said in the news conference that Schara has confessed to the murder. Investigators have not yet revealed a motive for the killing.
