Trick-or-treat murder plot ends in arrest

Deputies: Local woman arrested for plotting to kill her husband

SPOKANE, Wash. – A 39-year-old Spokane Valley woman was arrested for plotting to kill her husband.

Deputies arrested Martie M. Soderberg on Monday.

The incident was reported to the Spokane Valley Sheriff’s Office on Oct. 11 by a subject Soderberg asked to carry out her plan.  The subject told investigators he knew Soderberg from high school and had not talked to her since that time.

The subject said he and Soderberg has reconnected through social media and began chatting.

On October 11, the subject met with Soderberg for coffee at a restaurant in Spokane Valley. Soderberg said she had been married to her husband for 15 years. She said at first things were good but the marriage turned verbally and physically abusive.

Soderberg said she was done with the abuse and wanted her husband gone. She also said she was the beneficiary of her husband’s life insurance policy and indicated she could not just leave because she could not make it on her own. Court records show his life insurance policy was worth $300,000. 

Soderberg detailed a few different plans to kill her husband, both involving the subject.

The first plan was to have the subject shoot her husband on Halloween night while they were out trick or treating with their children.

The second plan, which she said was a “better” plan, would be to have her husband shot while he was at work. With the second plan, Soderberg stated she could collect L&I payments and the life insurance.

After leaving the meeting, the subject quickly reported this to deputies who then contacted detectives.

The subject worked with detectives, including wearing a recording device during the investigation.

During subsequent meetings, Soderberg described how the weapon could be disposed and suggested when the murder could take place in order to provide her with a strong alibi.

On Oct. 17, the subject met with Soderberg again. During this meeting, Soderberg gave money - $50 -  to the subject to purchase a firearm to carry out the murder.

Following the meeting, detectives contacted and arrested Soderberg. She was transported and booked into the Spokane County Jail for criminal solicitation to commit first degree murder with a $1 million bond. 

"There are plenty of other options than plan somebody's death," said Mark Gregory, from the Spokane County Sheriff's Office.
