On Feb. 3, 2015, Rob Dyke published an episode of the "SERIOUSLY STRANGE" series titled "Mysterious DEATHS | SERIOUSLY STRANGE" on his YouTube channel. In the video, Dyke talks about some controversial and puzzling cases of deaths which were never solved.

Dyke begins with the death of one Gareth Williams, an MI6 codebreaker and spy whose body was discovered in his flat after a week of not showing up at work. Williams was found in a bathtub, stuffed inside a padlocked sports bag without any wounds or signs of struggles on his body. The police have made hundreds of attempts to recreate the bathtub scenario as the question of how Williams could have padlocked himself in the bag was highly central to the investigation. After several unsuccesful attempts, the Metropolitan Police were more convinced about the possibility of foul play--however, they suddenly released a statement claiming that it was likely that no other person was in the flat at the time of Williams' death, and dismissed it as an act of suicide and left it at that. Many have deemed this evidence review to be false.

Next, Dyke tackles the 1932 case of a sex worker named Lily Lindstrom in Stockholm, Sweden. Lindstrom was found in her apartment three days after May Day festivities, drained of blood. The investigations that followed concluded that whoever had murdered Lindstrom had drank her blood using a soup ladle, and the killer whom they dubbed the "Atlas Vampire." The perpetrator had never been caught.

In 1974, a union activist and plutonium plant worker at the Kerr-McGee plant named Karen Silkwood was found dead inside her small white Honda, crashed in a ditch. Prior to her death, Karen had been collecting allegations regarding the safety and health conditions at the plant that she worked for and had been on her way to meet a The New York Times reporter, carrying evidence of said misconduct. The marks found on her car pointed to her being deliberately forced off the road by another vehicle. Prior to her death, Karen had been suffering from copious amounts of Quaaludes in her bloodstream, which yielded the question of how her body had been loaded with the substance.

At the end of the video, Rob Dyke says some parting words to the viewer and reveals that the clip is only one-half of a collaboration between him and Matthew Santoro, another YouTube personality who published a similar video titled "The 10 Most BIZARRE Deaths of All Time."
