A 14-year-old northwestern Wisconsin girl who said she was a psychopath looking for her first kill is accused of cycling to the home of her brother's girlfriend, beating the girl and slitting her throat.

Kali J. Bookey, of New Richmond, was charged as an adult with attempted first-degree intentional homicide on Thursday. She is currently being held without bond at a juvenile detention center.

Police say Bookey told investigators she wanted to scare the victim to leave the area.

Bookey's mother, Dawn Bookey, said in a brief telephone conversation Friday that there were no signs her daughter was planning to attack the girl and that her family is very, very sad.

Meanwhile, the victim continues to recover in the hospital from her 'very serious' injuries.

A criminal complaint filed Thursday says police were called to an area north of New Richmond, Wisconsin around 9:30am where they encountered Bookey.

Bookey told police that she had been riding her bicycle earlier that morning when two men wearing ski masks and armed with a knife starting assaulting her.

She said that she tried to ward off the attackers by telling them there was a residence nearby where a girl was home alone.

Police went to that address and found the 15-year-old victim bleeding profusely from the face and neck and yelling for them to get an ambulance.

Contrary to Bookey's story, the girl said that it was Bookey - her boyfriend's sister - who attacked her for hours, attempting to suffocate her, beating her and cutting her with the shards from a broken bowl.

Near the end of the attack, Bookey reportedly asked the girl if she wanted to 'die right now' or 'bleed out'. The victim chose bleed out and Bookey stopped cutting her.

Bookey then revealed her plans to the victim, saying she had planned the attack for the past week and a half, biking past the home for several days to make a note of when people came and went.

She allegedly referred to herself as 'a psychopath and that (the victim) was her first kill and she was probably going to kill again'.

As she was leaving, Bookey told the victim to 'have a nice afterlife'.

Bookey eventually dropped the men in ski hats story and copped to the attack, saying she had grown to hate the victim for how happy she made her 16-year-old brother.

She also added that she didn't intend to kill the victim, only scare her enough so that she moved away and her brother could be closer to his family again.

Bookey told police that she left her home around 4am and rode her bike 11 miles to the victim's home, arriving around 6:20am.

She entered the home through an unlocked sliding glass door and then proceeded to do breathing exercises in the living room.

Once she got her breathing under control, Bookey when into the victim's bedroom and woke her up by trying to suffocate her while wearing rubber gloves.

She then hit her 20 to 30 times and cut her about four times. Yet in the second hour of the attack, Bookey also got up to get the victim a glass of water when she requested it.

She also tried to cover up her footprints by forcing the victim to record a voice memo making it appear as if she was attacked by masked men.

Bookey said she didn't want to kill the victim and her initial call to police was all to get the victim help. She said she made up the abduction story to explain her numerous injuries.

When police encountered her, Bookey had swollen and bruised hands, scrapes on her knees and cuts and scrapes on her legs. When she appeared in court on Thursday, she sported a large bandage on her right hand.

Police said that Booker spoke about the attack in 'a calm, mostly unemotional manner'.

As of Thursday, the victim remained hospitalized at Regions Hospital in St. Paul. Police say her injuries were 'very serious'.

'If we didn’t find her when we did, I think there was the potential for them to be fatal,' Scott Knudson, chief deputy for the St. Croix County Sheriff’s Office, said.

In a post on Facebook late Thursday, the victim's boyfriend wrote that she is 'doing just fine' as she recovers at the hospital.

'She is very calm, and she is not at all shaken by it, just shocked my sister would do it,' the boyfriend wrote. 'She says she loves her scars because they look cool, and she's only upset that her favorite dress got ruined.'

He said that they had plans to get married as well, as early as next June, and she had already taken his last name on Facebook.

'As she was bleeding to death on her floor, she sent me a message asking to have Bookey on her tombstone instead of her last name,' he said.

In court on Thursday, Bookey's attorney, Barbara Miller, asked that she be released to her parents' custody.

'It’s way too early to talk about that,' St. Croix County Circuit Court Judge Eric Lundell said.

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

While Daily Mail Online does not usually name suspects who are minors, Bookey was charged as an adult.

In Wisconsin, juveniles accused of first-degree homicide or attempted first-degree homicide, who are over the age of 10, can be tried as adults.
