College student Anita Knutson was found stabbed to death in her bed in a haunting mystery that would take nearly two decades to be resolved.

The unexpected death of an 18-year-old in Minot, North Dakota, and the tireless quest by her family and friends to seek justice will be the focus of a brand-new episode of Dateline. This episode is scheduled to air on Friday, May 2 at 9/8c p.m.

The episode will explore the shocking death of Staten Island teacher Simeonette Mapes-Crupi, who was found dead in her home on July 5, 2012.

“Beloved Staten Island teacher Simeonette Mapes-Crupi is discovered lifeless at the foot of the stairs in the residence she shared with her spouse, Jonathan,” reads the episode’s summary. “A mysterious number found on her cell phone prompts investigators to uncover issues within her seemingly perfect life and eventually identify her murderer.”
