Warning! This article contains spoilers for Your Friends & Neighbors' episode 6.

Paul's unexplained death remains one of the biggest mysteries in Your Friends & Neighbors, but the show has seemingly dropped enough clues for viewers to theorize who might have killed him. Your Friends & Neighbors opened with a flash-forward scene in which Jon Hamm's character found himself next to a man's dead body. In this scene, he desperately tried to hide the evidence of his presence at the crime scene before recalling all the events that led him to the moment.

After walking through all the little developments that led the character, Andrew Cooper, to the crime scene, Your Friends & Neighbors' episode 5 finally circles back to the opening moment. This not only confirms the identity of the dead man but also raises many questions about who might have killed him. The scene makes it obvious that Jon Hamm's Andrew Cooper likely had little to do with Paul's demise. However, he might have to figure out the truth about Paul's murderer's identity before law enforcers find leads that make him a primary suspect in the case.

Your Friends & Neighbors Season 1 Episode 5 Confirmed Paul Was The Mystery Victim

Episode 5's Ending Also Revealed Cooper Had Nothing To Do With His Murder

After a night of clubbing, which leads to a fallout between Cooper and Elena, Cooper decides to text Samantha to ask her if she is available in episode 5's final arc. To his dismay, Elena reveals she has left town with her children. Cooper takes Sam's absence as an opportunity to sneak into her home and steal something. Unbeknownst to him, someone visits Sam's house before him and commits a heinous crime. Moments after Cooper enters the house, he slips on some blood on the floor, hits his head on the ground, and loses consciousness.

When he later awakens, he finds himself lying in a pool of blood next to Paul's dead body. The show previously revealed that Paul was Sam's ex-husband, which could explain what he was doing at Sam's house in her absence. However, the show is yet to reveal the identity of the person who killed him.

If Paul's killer was not just another thief, the murder raises many questions about the true motivations behind the crime.

Although characters from Your Friends & Neighbors can be seen as potential suspects.

Who Killed Paul In Your Friends & Neighbors?

Sam Seems The Most Obvious Suspect

Since Sam was gradually growing resentful towards her ex-husband, she has to be seen as the main suspect. However, Sam being the killer would be a little too obvious. Given how Cooper has been a reliable narrator so far, he seems not to have contributed directly to the murder. However, his criminal endeavors might have triggered a chain reaction of events that led to the crime.

Your Friends & Neighbors has also established that, other than Cooper, even characters like Mel and Barney are desperately trying to stay afloat despite surrounding themselves with a lavish lifestyle. This makes them suspects as well, since they, too, might have tried to break into Samantha's house to steal something before running into Paul. Your Friends & Neighbors' season 1 will likely delve deeper into this mystery in its episodes while walking through Andrew Cooper's downward spiral and struggles with morality.
