EVERETT — An Everett man shot twice in the head during an apparent Oct. 21 robbery has recovered sufficiently to speak with detectives.

He tells a different story than the woman charged last week with the attack, court papers show.

Marissa Elizabeth Wallen, 21, was charged Friday with first-degree assault and first-degree robbery.

In a brief Snohomish County Superior Court appearance Tuesday afternoon, she entered not guilty pleas to both counts.

Her defense attorney, Jon Scott, reserved the right to make any arguments to try to reduce her $1 million bail.

Judge George Appel set a trial date for Feb. 9.

The Mount Vernon woman, who reportedly works as an escort, is accused of shooting the Everett man twice in the head and then leaving his home with his wallet. The victim, 36, was left for three days without medical attention.

Wallen has been locked up since November after Everett detectives tracked her down in Skagit County. She was using one of the victim’s stolen credit cards and was recorded on surveillance video as the last person inside the man’s home, deputy prosecutor Katie Wetmore said in an affidavit filed along with the charges.

A .380-caliber handgun believed used in the attack was found during a search of the home where she was staying. The weapon was partially loaded with bullets that reportedly match the make and model of a shell casing found at the shooting scene.

After her arrest, “the defendant provided several accounts of what happened, but changed each time she was confronted with the evidence,” Wetmore wrote.

Wallen eventually told detectives she shot the man in the back of the head “because he was performing (a sex act) wrong,” according to court papers.

The man who was shot provided another version of events. He was interviewed by detectives at a rehabilitation facility where he has been recuperating from the gunshot wounds, the prosecutor wrote.

He told investigators that he met Wallen online on sites that advertise for people seeking a “sugar daddy.”

The man admitted he gave Wallen money, but denied he paid her for sex. He told them that he was shot while she gave him a back rub, Wetmore wrote.

After the first shot, “the defendant began demanding money and (the man) explained that he could not get her any because she had shot him,” the prosecutor wrote. “The defendant threatened to shoot him again if he did not give her money and he responded that he could not, so the defendant shot him again.”

The man was found after people became concerned when he didn’t report to work for three days.

Detectives determined that about $12,000 was stolen from his accounts, court papers say.
