High School Sweethearts Murdered In A Subway On Valentine's Day & There's Still No Justice

·1 hr 10 min·5 clips

Two high school sweethearts were shot execution-style in a Subway on Valentine's Day 2000, and the killer has never been found.

The episode begins by introducing the unsolved 2000 murders of Stephanie Hart Grizzell and Nick Kunzelman, two high school sweethearts shot in a Subway in Littleton, Colorado on Valentine's Day. Hosts Kendall and Josh, with producers Ian and Janelle, provide background on Littleton's history and its connection to the Columbine High School shooting, which both victims survived. They describe Stephanie as a 'flower child' who disliked technology and Nick as a musician, emphasizing their young age and close relationship. The narrative details the night of the murder: Nick was closing the Subway alone, Stephanie sneaked out to join him, and they were found dead by an employee who also saw a potential suspect fleeing. The investigation collected over 150 pieces of evidence, but the security camera was intentionally turned off, likely to hide drug activity at the location. A DEA probe led to 35 drug-related arrests but no murder suspects. The hosts discuss Stephanie's mother Kelly's lawsuit against the Subway owner, which was dismissed, and her altercation with police that strained relations with investigators. They explore theories including an attempted robbery, drug-related crime, and a Columbine copycat, debating the likelihood of each based on the execution-style shootings and the suspect's description. The episode connects the case to other unsolved crimes: the disappearance of Brandy Jo Mallinson, a former Subway employee who may have discovered the bodies, and a 2002 triple homicide at a bowling alley. Despite 40 binders of evidence and a $100,000 reward, the case remains cold, with the hosts urging listeners to submit tips. They conclude by noting the victims are buried together and their families visit annually on Valentine's Day.
