Unable to solve the 1992 murder of an Agawam, Massachusetts woman, the Hampden District Attorney’s office has paid a contractor to create a computer-generated image of a suspect.

Using a technology known as DNA phenotyping, it’s based on DNA evidence found at the scene of Lisa Ziegert’s murder 24 years ago. Hampden District Attorney Anthony Gulluni said the new image has revealed some identifying features including skin, hair and eye color.

“This is not something that’s going to be used as evidence. It’s used in the criminal investigation stage to generate leads, to exclude suspects,” Gulluni said. “This is going to be used by investigators to great effect in the weeks and months to come as they take another view of the case in light of this forensic development.”

Gulluni declined to specifically say how much his department paid to have the image created. However, he said the cost is “not going to blow anyone’s socks off, but it’s not cheap either.”
