Patrick Fowler, 31, has been arrested after he allegedly stabbed his girlfriend and her daughter to death and set their house on fire

A Milwaukee man has confessed to stabbing his girlfriend 26 times, killing her daughter and then lighting their house on fire with coloring books because he 'felt disrespected', police said.

Patrick Fowler, 31, has been charged with two counts of first-degree intentional homicide in the deaths of Jessica Ellenberger, 28, and her four-year-old daughter Madyson Marshel.

Fowler told police he and Ellenberger got into an argument and that he 'felt as if he were being disrespected', according to the complaint.

When Ellenberger told him to 'back off' Fowler allegedly began to stab her, telling police he was unsure of how many times but that he 'kept on and kept on'.

Fowler then realized his girlfriend was still alive and grabbed more knives, continuing to stab her before he slit her throat.

As Madyson, a recent cancer survivor, screamed out 'Mommy!', Fowler then began to stab the little girl too.

After he knew both women were death, Fowler contemplated killing himself but then decided to set the house on fire instead, he told police.

Since there was no lighter fluid in the house, he used Madyson's coloring books to ignite the blaze.

He noted to police that he took the Easter candy inside the residence before he walked out as the house went up in flames.

An autopsy found 26 wounds on Ellenberger's upper body. Madyson was stabbed twice and was burned over 100 percent of her body (the pair are pictured with Madyson's father Christopher Clark)

An autopsy found 26 wounds on Ellenberger's upper body, plus burns on 40 percent of her body. Madyson was stabbed twice and was burned over 100 percent of her body.

Fowler told police he 'did not feel bad for any of the decisions that he made'.

US marshals arrested Fowler during a bus layover in Texarkana, Arkanas earlier this week. His extradition to Wisconsin remained pending on Friday.

Fowler was on probation for threatening to kill his fiancee and her son with knives after she broke off their engagement six months ago, according to WISN.

Christina Thomas told the news station that Fowler told her: 'We're all going to die tonight. First your son, then me. Nobody lives, nobody.'

Thomas now said she feels guilty for Ellenberger's death.

'Jessie should be alive,' she said. 'That if I just wouldn't have moved, and let him slit my throat, that I would be dead and she would be alive because he would have went to prison for good.'

Fowler's mother was arrested after it was discovered she had bought her son a ticket to the bus station and knew he had killed Ellenberger and her daughter. She has not been charged.

Ellenberger was a protection officer at a security company.
