September 4, 1977. Ewing Township, New Jersey. The nude body of 25-year old graduate student Sigrid Stevenson is discovered beneath a piano cover inside the Main Stage Theater of Kendall Hall on the campus of Trenton State College. She has been bludgeoned to death with a blunt object and since Sigrid had been staying in Kendall Hall that weekend, she was likely attacked while practicing the piano on stage. A number of people are looked at as potential suspects, including campus police officers, campus staff and members of a theatre group, but there is no conclusive evidence to implicate any of them and Sigrid’s murder remains unsolved. On this week’s episode of “The Trail Went Cold”, we explore a cold case that was recently featured on the Netflix reboot of “Unsolved Mysteries”.

If you have any information about this case, please contact the Mercer County Homicide Task Force at (609) 989-6406.
