TACOMA, Wash. -- Terapon Adhahn, the man suspected in the kidnapping and death of Zina Linnik, was charged Wednesday with the unrelated rape and kidnapping of an 11-year-old Tacoma girl in 2000.

Pierce County prosecutors also filed charges alleging he raped another girl dozens of times over a period of four years.

According to charging documents, Adhahn allegedly kidnapped an 11-year-old girl while she was walking to school on May 31, 2000.

Adhahn allegedly grabbed the girl, taped her hands together and covered her mouth and eyes with tape.

He then drove her to a secluded training area on Fort Lewis where he threatened the girl with a knife and repeatedly raped her for over an hour, the documents said.

Adhahn left the girl on a street with her eyes taped shut and her hands taped together.

The girl was found by a Tacoma police officer about 10 a.m. walking on Fort Lewis road.

The victim sustained injuries during the assault that required hospitalization and surgery.

DNA evidence was recovered, but could not be matched to a suspect at the time. Charges were filed against a "John Doe" suspect in 2002 based on the DNA evidence.

Adhahn, 42, was arrested last week for the kidnapping of Zina Linnik and a DNA was expected to be taken from him, but it was not immediately known if that was how Adhahn was connected to the 2000 rape.

He is also expected to be charged in the kidnapping and death of Zina Linnik, who was taken from behind her home on July 4.

He provided the information that led police and FBI agents to the body and he was being held by federal immigration authorities. He was transferred to the Pierce County jail Wednesday afternoon.

Linnik died of "homicidal violence," the Pierce County medical examiner's office concluded.

She disappeared July 4 after being sent down an alley behind her home to bring back some of her siblings, who had wandered off to watch fireworks. Her father heard her scream, found a single flip flop on the ground and saw a boxy gray van driving away. His partial recollection of the license plate number led investigators to Adhahn.

Pierce County prosecutors on Wednesday also filed charges against Adhahn for allegedly raping a young girl dozens of times over a period of four years.

The girl lived with Adhahn for several years beginning in 2000 after she left her mother's care. She told investigators that she knew Adhahn as a friend of her mother's boyfriend.

According to charging documents, the victim said the rapes began when she was 12 years old and happened "too many times to count."

The girl said she ran away when she was 16 after she was raped by Adhahn at gunpoint. She was contacted by FBI agents in Kansas after Adhahn was arrested in the Linnik case.

On Tuesday investigators in Lakewood said Adhahn is a "person of interest" in the death of Adre'Anna Jackson, who was found dead in a Pierce County field in 2006.

Lakewood Police Lt. Dave Guttu said officers went back and showed Terapon Adhahn's photo to residents in the Tillicum neighborhood where Adre'Anna lived, and several people said they saw him in the area around the time Adre'Anna disappeared.

Police found "he is commonly known as a handy man in that area," Guttu said. "Stores or apartment complexes or individuals have used him as a handy man."

The 10-year-old girl was last seen alive when she left for school December 2, 2005. Her remains were found April 4, 2006 by two young boys who were playing in a field.

Adhahn served two months in jail and completed five years of sex offender treatment following a 1990 incest conviction after he violently raped a female relative, according to court records.

During an evaluation in August 1990, Adhahn told a therapist he'd been sexually molested countless times by an older brother when he was between the ages of 7 and 9 years old, according to court records. He also said his biological father was an abusive alcoholic.

The therapist called Adhahn's personality profile "extremely problematic." But by the time Adhahn completed sex offender treatment in 1997, his counselor wrote that he had made adequate progress and was actively involved in weekly group therapy.

Adhahn, a legal permanent resident of the U.S., could not have been deported for the incest conviction because it was not an aggravated felony and it was his first offense, U.S. Immigration and Customs Enforcement spokeswoman Virginia Kice said.

But a 1992 conviction for intimidation with a dangerous weapon could have made him deportable, and Adhahn was being held this week on an immigration complaint. He also was charged with failing to register as a sex offender.

The cases being reviewed by police date back more than 20 years. Michella Welch, 12, of Tacoma, was found dead hours after the girl disappeared from a park on March 26, 1986. Later that year, Jennifer Bastian, 13, of Tacoma, was found dead in a park where she'd been last seen riding her bicycle two weeks earlier.

Investigators around the country are also reviewing other unsolved cases to see whether Adhahn may have been in the area at the time
