Pete Daily, also known as the Whisper Killer, was a journalist and secret serial killer, who served as a minor antagonist in Season 5. He was in a brief romantic relationship with Ella Lopez, albeit being serious. However, his killings never stopped and his relationship with Ella eventually leads to his arrest and imprisonment after she discovers his secret room.
During his childhood, Daily's mother would scream at him constantly. This, combined with the fact that he felt like she loved her lily garden instead of him, eventually lead him to develop a deep hatred towards loud and talkative women, and a desire to silence them by cutting their vocal cords after first paralyzing them.
While trying to report on the murder of a DJ, he met Ella Lopez who helped him get more information for his article. After a friendly invitation to go out by Daily, Ella rejects him, although she would later ask him out, after realizing she deserved a nice guy.
After Chloe Decker was kidnapped by Michael, Ella and Lucifer Morningstar suspect the original "Whisper Killer" is involved. As per his suggestion, Ella went through Daily's notes about the serial killer, and found a secret room in Daily's apartment where he kept dozens of lilies that matched the killer's calling card exactly. Ella deduced that Daily was the real serial killer. When he arrived home soon after, he realized that Ella had discovered his secret room, tackled her to the ground, and tried to strangle her. Ella got the upper hand by stabbing him in the back with one of his paralytic syringes.
He was later brought to the LAPD precinct, where he was interrogated by Ella, and he coolly revealed his motive for the murders. Although he felt no remorse for his actions, he was honest and admitted to not knowing the whereabouts of Chloe Decker, who was still missing.
