Suspect Arrested for Plotting to Kill Her Husband


Spokane Valley Sheriff’s Detectives arrested 39-year-old Martie M. Soderberg (aka: Maxwell) for Criminal Solicitation to commit 1st Degree Murder, Monday afternoon.

The incident was reported to Spokane Valley Sheriff’s Deputies on October 11th, 2016 by a subject Soderberg asked to carry out her plan.  The subject told investigators he knew Soderberg from high school and hadn’t talked to her since that time.  He said recently, they reconnected through social media and began chatting.

On October 11th, he met with Soderberg at a restaurant for coffee in Spokane Valley.  It was during that conversation Soderberg told the subject she had been married to her husband for 15 years.  She stated at first things were good but the marriage turned verbally and physically abusive.  She explained she was done with the abuse and wanted her husband gone.  She said she was the beneficiary of her husband’s life insurance policy and indicated she couldn’t just leave him because she couldn’t make it on her own.

Soderberg detailed a couple different plans to kill her husband, both involving the subject.  The first plan she described where the subject would shoot her husband on Halloween night while they were out Trick or Treating with their children.  The second and “better” alternative would be to have her husband shot while at work.  With the second plan she stated she could collect L&I payments, as well as the life insurance.

The subject left the meeting and quickly reported this to deputies who then contacted detectives.  The subject agreed to work with detectives, including wearing a recording device during this investigation.

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

On October 17, 2016, the subject again met with Soderberg.  During the meeting she gave money to the subject to purchase a firearm to carry out the murder.

After the meeting, Detectives contacted and arrested Soderberg.  She was transported and booked into the Spokane County Jail for Criminal Solicitation to commit 1st Degree Murder with a 1 million dollar bond.
