Who is Claire Miller, the TikToker who murdered her sister?

In March 2023, Claire Miller entered a guilty plea for the fatal stabbing of her sister, Helen.

By February 2021, 14-year-old Claire Miller had gained popularity on TikTok, amassing around 22,000 followers through her lip-synch videos. Despite her online success, her offline life at Lancaster Country Day School in eastern Pennsylvania among 550 indifferent students was marked by her often overshadowed existence as the younger sibling of her 19-year-old sister, Helen, who lived with cerebral palsy.

Helen had been assisted by Claire for years. However, on February 22, 2021, Claire reached a breaking point and unexpectedly stabbed Helen to death with a kitchen knife while she peacefully slept. Claire called the police, who arrived as her parents were waking up.

Manheim Township Police Chief Tom Rudzinski expressed the profound sadness of the situation, stating, “I don’t know that I have ever been a part of something that is quite as sad as this.”

Born in 2007 in Lancaster, Pennsylvania, Claire Elaina Miller was raised by loving parents Mark and Marie Miller. While she enjoyed good health, her older sister Helen, diagnosed with cerebral palsy, required constant assistance due to being wheelchair-bound.

Both sisters attended Lancaster Country Day School, where Claire spent her post-school hours posting videos on her TikTok account, @spiritsandsuchconsulting. Her content ranged from harmless lip-synching to more ominous videos. Following her arrest, her TikTok following grew rapidly.

In a particular video, Miller shared screenshots from a Japanese video game series named Danganronpa, depicting a scenario where a group of high school students is manipulated into committing murder by a creature named Monokuma. Miller posted a video featuring screenshots from a Korean comic titled Killing Stalking, narrating the story of a young man who, grappling with mental illness, undergoes abuse and assault from his uncle during his military service. Furthermore, another video showcases Miller lip-syncing to the song “Violent” by Carolesdaughter.

The tragic events of February 22, 2021, unfolded as Claire entered Helen’s room around 1 a.m. armed with a kitchen knife. She stabbed Helen multiple times in the neck, followed by placing a pillow over her face. Claire called 911 at 1:08 a.m., admitting to the crime. Police arrived within minutes, finding Claire outside in blood-soaked clothing.

Claire’s appearance, her attempt to clean her hands, and the bloody crime scene raised suspicions. Helen was found dead. Claire was taken into custody and charged with criminal homicide. She will be tried as an adult, as Pennsylvania does not consider murder a delinquent crime.

In a TikTok video discovered after the crime, Miller seems to display a white latex glove stained with blood against the snowy backdrop, then shifts the focus to a plush giraffe toy also covered in blood.

Despite Claire’s defense seeking a potential insanity plea and a transfer to juvenile court, her guilty plea on March 10, 2023, solidified her fate. Though ruled mentally ill but not mentally disabled, Claire faces imprisonment for a period ranging from 12.5 to 40 years.

The tragedy garnered widespread attention, with Claire’s TikTok following skyrocketing following the murder, before her account was eventually removed by TikTok.

District Attorney Heather Adams said, “This certainly is an incredibly tragic and unusual case. Our sympathies are with this family as they try to cope with the impact of this crime. Investigators will continue to process and analyze evidence to determine the circumstances that led to the victim’s death.”
