12-Year-Old Girl Accused of Trying to Poison Mother for Taking Away iPhone The 12-year-old is in custody on two counts of attempted first-degree murder.

 -- A 12-year-old Colorado girl has been detained for allegedly trying to kill her mother twice by poisoning her drinks with bleach, after her mother took away her iPhone, police said.

The woman first felt sick on March 2, after drinking a smoothie, according to the Boulder County Sheriff's Office. While she noticed the smell of bleach from her glass, the woman assumed her daughter hadn't rinsed it properly, according to the sheriff's office.

Then a few days later, the mother again recognized the smell of bleach coming from something she was going to drink and she confronted the pre-teen, the sheriff's office said. The girl allegedly told her she wanted to kill her because she took away her iPhone, according to the sheriff's office.

The girl had allegedly poured bleach into her mother's water carafe, the sheriff's office said.

On March 6, the mother was at the Boulder Community Hospital when she contacted authorities to investigate.

The woman is no longer in the hospital and is in fine condition, the sheriff's office said today.

On Friday, the 12-year-old was detained at the Boulder County Juvenile Center on two counts of attempted first-degree murder, according to the sheriff's office.

"She had pre-planned this a couple different times," Sgt. Bill Crist of the sheriff's office said.

The investigation is ongoing, and the District Attorney's office will decide what charges to pursue, according to the sheriff's office.
