A 12-year-old Boulder County, Colorado, girl is accused of trying to kill her mother on two separate occasions with bleach, after she took away her iPhone.
The girl first tried to kill her mother on March 2 by pouring bleach into her smoothie, police told NBC affiliate KUSA. The mother told police she smelled bleach in the drink, but thought her daughter had cleaned the glass and didn't rinse it thoroughly.
Later that week, police said, the girl put bleach into a water carafe her mother kept in her bedroom. That's when the mother confronted her daughter.
During the confrontation, the daughter told the mother she planned to kill her because the mother took away her iPhone, police said.
"Most kids don't try to kill their parents," a police official said, according to KUSA. "We're not sure where she came up with the idea to do it the way she did."
The mother was taken to hospital, where police were notified. She was not injured.
The girl was arrested on March 20 on two counts of attempted first-degree murder and is in a juvenile detention center. Charges haven't been filed, according to KUSA.
