14-Year-Old Girl Allegedly Attempted to Kill Brother's Girlfriend to Get Her to Leave Him Alone

A 14-year-old Wisconsin girl will be tried as an adult for the alleged attempted murder of her older brother's girlfriend, the Eau Claire Leader-Telegram reports.

Kali J. Bookey of New Richmond was charged Thursday with attempted first-degree intentional homicide and is in juvenile custody after she allegedly attacked the 15-year-old victim and slit her throat with shards of ceramic bowls on Wednesday, according to the Leader-Telegram.

A criminal complaint obtained by the newspaper alleges that Bookey called police Wednesday morning to report an attempted abduction. When police arrived at her location, she sent them to a New Richmond home to follow her alleged attackers. Upon arriving at the second address, police found Bookey's victim bleeding from the face and neck, according to the complaint.

A Wednesday press release from the St. Croix County Sheriff's Office states that over the course of the investigation, "information was gathered that leads our office to believe that the individuals being treated were the only ones involved in this incident," and that no attempted abduction had taken place.

According to the criminal complaint, the victim told police that Bookey tried to suffocate her and repeatedly struck her in the head and face before breaking a pair of ceramic bowls over the victim's head and using the pieces to cut the victim's throat.

Bookey reportedly told her victim she "was a psychopath and crazy and that [the victim] was her first kill and she was probably going to kill again," according to the complaint.

Bookey allegedly told police that she had arrived at the victim's residence around 6:20 a.m. on Wednesday morning and entered with the hope of scaring the victim into moving away from the area and leaving Bookey's brother and family alone, according to the complaint.

The Twin Cities Pioneer Press reports that St. Croix County Circuit Court Judge Eric Lundell ordered Bookey to be held in juvenile custody and refused Bookey's attorney Barbara Miller's request for her client to be released into family supervision. Miller did not immediately respond to PEOPLE's request for comment and it is not known how Bookey plead agains the charges.

Both girls were injured, the Pioneer Press reports. Bookey appeared in court Thursday with a large bandage on her right hand and Chief Deputy Scott Knudson said Bookey's victim had sustained "very serious injuries" and continued to recover in a nearby hospital.

According to the Associated Press, Bookey's family had no knowledge of her allegedly violent intentions.

Bookey's mother Dawn told the AP in a brief phone call that there were "no signs" Bookey planned to attack her brother's girlfriend and that the family was "very, very sad" about the incident.

Bookey is due in court for a preliminary hearing on Aug. 8.
