Quick Read

This 48 Hours episode reconstructs three distinct cases of individuals dying under suspicious circumstances involving partners, drugs, and alleged cover-ups, each revealing complex relationships and the pursuit of justice.
Google executive Forest Hayes died from a heroin overdose on his yacht, with his online 'sugar baby' Alex Tickleman present, who cleaned the scene and left him to die.
Dr. Chris Kulis, a plastic surgeon, was convicted of criminally negligent homicide for his girlfriend Lisa Buchanan's overdose death, having supplied and injected her with drugs, only to die of an overdose himself.
Eileen Seiden was brutally murdered by her 'thropple' partners, Zachary Ael and Christina Ajo, after a violent road trip fueled by alcohol and jealousy.

Summary

The episode presents three separate true-crime investigations. The first details the 2013 death of Google executive Forest Hayes from a heroin overdose on his yacht, leading to the arrest and conviction of Alex Tickleman, a 'sugar baby' he met online, who was also linked to another overdose death. The second case covers the 2005 death of Lisa Buchanan from an oxycodone overdose, with her plastic surgeon boyfriend, Dr. Chris Kulis, accused of supplying and injecting her with drugs. Kulis, who had a history of drug abuse and had previously addicted Lisa, was convicted of criminally negligent homicide but died of an overdose himself before serving time. The third story investigates the brutal 2018 murder of Eileen Seiden, whose body was found dumped after a violent 'thropple' relationship with Zachary Ael and Christina Ajo. Both Ael and Ajo were convicted of second-degree murder, with Ajo becoming a star witness against Ael.
These cases highlight the hidden dangers within complex, often secretive, relationships involving drug abuse and manipulation, demonstrating how personal choices and the actions of others can lead to tragic outcomes and challenging legal battles for justice.
