Terapon Adhahn will be arraigned Monday on a charge of aggravated first-degree murder for his alleged role in the abduction and death of 12-year-old Zina Linnik, according to the Pierce County prosecutor.

A charge of aggravated murder could result in prosecutors seeking the death penalty. Prosecutors have not said whether they will be seeking Adhahn's execution should he be found guilty.

Adhahn, a 42-year-old construction worker, was identified last week by Tacoma police as the suspect in Zina's July 4 kidnapping and slaying.

Zina was abducted from an alley behind her home, police said. Witnesses provided police with a partial license-plate number of a gray van seen leaving the area. Armed with that information, a Tacoma police detective tracked down Adhahn after a computer search, police said.

Zina's body was found July 12 near Silver Lake, west of Eatonville in eastern Pierce County.Adhahn, through his attorney, gave detectives information that led to the discovery of the body, police said.

Meanwhile, Adhahn stood with his head bowed in a Pierce County courtroom Thursday as his attorneys repeated the words "not guilty" on his behalf to a litany of charges stemming from the sexual assault of two girls.

A judge set bail at just over $2 million for Adhahn, who is charged with seven counts of rape for repeated assaults against a girl who lived with him for four years and three counts of rape and one count of kidnapping in connection with an attack on an 11-year-old girl in 2000.

Behind a glass partition, relatives of Zina's and the victim in the 2000 rape stared intently at Adhahn, a slightly built man who wore an orange jail jumpsuit during the brief hearing.

The sister of the girl Adhahn is accused of raping in 2000 said the family came to see him to make sure "he was the guy." She said the family feels enormous relief now that there has been an arrest in the case.

The girl's mother said her daughter looks forward to facing Adhahn in court.

"She's more mad than anything else," her mother said.

The Seattle Times is not naming either woman to protect the identity of the rape victim.

Zina's family declined to comment.

Adhahn was also arraigned Thursday on one count of failing to register as a sex offender in connection with a 1990 conviction for first-degree incest.

According to Pierce County Superior Court documents, Adhahn allegedly abducted the 11-year-old girl while she was walking to school alone on May 31, 2000. Prosecutors say Adhahn threatened the girl with a knife, duct-taped her hands, mouth and eyes and then drove to a remote training area in woods on the Fort Lewis base, where he repeatedly raped her.

A DNA sample was taken from the victim. Pierce County Deputy Prosecutor Ed Murphy said a crime lab has matched the DNA sample to Adhahn.

Adhahn is also charged with repeatedly raping a girl who moved in with him in 2001 when she was 12 because her mother had unspecified "troubles" that made her unable to care for her. The girl, now 19 and living in Wichita, Kan., told Tacoma detectives she was raped at least 150 to 200 times over the course of the four years she lived with the man she called "Dad."

The attacks stopped only when she fled his home at 16 after he raped her at gunpoint when she tried to refuse him, court documents allege.

Police are also investigating Adhahn in connection with several other attacks on young girls in and around Tacoma dating back more than a decade.

Police have told the parents of Adre'Anna Jackson that Adhahn is being investigated as the primary suspect in their daughter's death. Her remains were found in a vacant lot near Tacoma four months after she disappeared while walking to school in December 2005.
