Twenty-four years ago the body of 27-year-old Susan Taraskiewicz of Saugus was found in the trunk of her car at an auto body shop on Route 1A in Revere. State Police and Taraskiewicz's mother continue to ask for information in solving her murder and will again produce a video asking for help.

Taraskiewicz's body was found on Sept. 14, 1992 after her car had been left at the auto body shop. The ramp supervisor for Northwest Airlines at Logan International Airport had left to go pick up sandwiches for co-workers and never returned. Authorities discovered she had been badly beaten.

"At the time of her death, other Northwest ramp employees were involved in a major credit card theft ring," State Police said in a Facebook post Wednesday. "Susan, who had endured vicious harassment from her co-workers, was not part of the ring."

Marlene Taraskiewicz, the victim's mother, will be speaking to State Police as officials there produce a video about the case. Marlene had been part of a video in 2014 where she asked for help and information about the case.

"Please come forth, it's not too late. It's never late to solve a murder," she said in 2014. "A murder case is always open. I am a very healthy woman and I am not going away. You're going to look over shoulder until the day that I go, but I will get you and I will get justice for my Susan."

Clear Channel Outdoor is donating electronic billboard space, starting Sept. 14, to help solicit information about the case. The new video and the billboard will be posted on the State Police's Facebook page and other media platforms in the coming days.

"Susan was beautiful, intelligent, friendly and had a heart of gold," her mother said in the 2014 video.

The State Police, Revere Police and the Suffolk County District Attorney's Office investigated the murder. Authorities pursued several leads and theories, but the case remains unsolved.

"Today, nearly a quarter of a century after her homicide, Susan's case remains extremely active," State Police said. "Investigators work the case every day, and know that there are people with knowledge of the murder who have not yet told what they know. Justice for Susan is long overdue. Help us speak for her and bring some peace to her family."

Anyone with information is asked to call the Massachusetts State Police at (617) 727-8817.
