A Pennsylvania man allegedly sent graphically violent notes to his neighbor, prompting police to call him a “potential serial killer.”
Dylan Bish, 19, was arrested by Koppel Borough Police on March 13 after an investigation into a series of notes reported by a woman. According to a Facebook post announcing the arrest, Bish allegedly sent a handwritten note to a female neighbor who lived nearby.
According to police, the note mentioned Bish’s alleged desires, which included wanting to “dismember” her body “with a chainsaw” and having “sexual desires with her corpse.” He also allegedly claimed that he had killed 20 women and that she was his “next victim.”
According to the police statement, Bish’s alleged fantasies extended beyond his handwritten notes.
According to the Facebook post, when police interviewed Bish after reading him his Miranda rights, he stated that he was obsessed with the woman to whom he allegedly sent the notes and did not intend to “stop his obsession until she is ‘dead.'”
Bish also told police “in detail” that he “wished to dismember her this summer in the woods.”
During his police interview, Bish reportedly stated that he was studying criminal justice and forensic science “for the sole reason” of learning how law enforcement, including the FBI, operates in order to avoid being “caught.”
According to police, Bish allegedly left the first note for the woman in November 2024. The details of that note were reportedly less graphic, and it appeared to be an attempt to get the woman to contact him.
The note addressed the woman by name and contained a phone number that was later discovered to be Bish’s. The alleged target of Bish’s note discovered the note at her home and reported it to police.
The next note, allegedly written by Bish, was left at her door and contained graphic, violent language. Court documents obtained by WPXI, a local NBC affiliate, stated that the second note allegedly contained the writer’s desire to dismember her body and “eat her brain.”
The author also stated in the note, “I’ve been watching you from my POV [in] front of your apartment [your] room is filled with CDs.” WPXI reported that the alleged victim had vinyl records on display in her home.
The violent nature of the second note prompted state police to launch an investigation into who was writing the notes.
WPXI reported that on March 10, police received a text from the phone number listed in the first note.
According to court documents, the text was intended for the alleged victim and stated that she would be his next victim, among other “gory details,” such as a desire to “smash her skull.” Police also obtained a graphic video of someone being skinned and tied up.
At this point, police alerted the alleged victim and contacted Beaver County detectives. Officers identified Bish as the alleged writer of the notes and text after using his phone number, email address, and IP address.
During his police interview, Bish allegedly confessed to sending the notes but stated that he never hurt anyone, despite claims of killing 20 women, and that he was “lonely and hoping for a relationship of friendship” with his alleged target.
Police and other agencies believed that a “homicide as well as the spawning of a potential serial killer may have been prevented in this arrest given the numerous homicidal details disclosed during Bish’s interview.”
According to Koppel Borough Police, Bish was arrested and booked into the Beaver County Jail, where he is being held on a $1 million bond.
A magistrate judge ordered him to have a mental health evaluation before being released. Bish was charged with stalking, making terroristic threats, harassing, and communicating anonymously. He is scheduled for a preliminary hearing on March 28.
