A teenage girl has admitted to killing her father in his Spokane home last year.

Jacqueline A. Wortham, 18, faces 22 years to life in prison after pleading guilty to first-degree murder. Her sentencing is scheduled for Sept. 16.

Daniel Wortham, 39, lived with his daughter on East Sharp Avenue when police say the girl and her boyfriend, Edmund D. Washington, 19, stabbed and beat him to death March 21, 2008.
