The King County Sheriff's Office has made an arrest in a cold case that is more than 20 years old.
Sarah Yarborough was a 16-year-old honor student when she was raped and murdered Dec. 14, 1991, near Federal Way High School.
She was last seen leaving her home to go to a high school dance competition. Her car was found in the school parking lot and her body was discovered in a wooded area on campus later that day.
The suspect in the case is 55-year-old Patrick Leon Nicholas, according to police. He was booked into the King County Jail Wednesday night.
The day of the murder, witnesses worked with investigators to help create a sketch of a potential suspect seen shortly before Yarborough's body was found, partially hidden, near the school's tennis courts.

Last year, a company called Parabon Nanolabs used DNA markers and genetics to create a series of composite sketches to predict what Yarborough's killer may have looked like at ages 18 and 25, and how he may look today.
