PORT ORCHARD — Two Kitsap County residents have been arrested in connection with the drug overdose death of a South Kitsap resident.

Larry Reinhold Mase Jr., 33, of South Kitsap, and Alyssa Suanne Doering, 19, of Gig Harbor, are in custody after warrants were issued charging the pair with “controlled substance homicide” in the death of Heather Marie Marion-Santos, 43, of South Kitsap, according to a press release from the Kitsap County Sheriff’s Office.

The cause of Marion-Santos’s April 30 death was determined to be “acute heroin and methamphetamine intoxication” following the completion of autopsy and toxicology reports. Investigators determined Mase and Doering had provided the drugs to Marion-Santos, prompting the issuance of their arrest warrants, police said.

Doering was arrested by the Bremerton Police Department on Aug. 6 during a shoplifting report at the Goodwill store on Wheaton Way. Officers discovered the homicide arrest warrant and took her into custody, Deputy Sheriff Scott Wilson said.

Doering was booked into Kitsap County Jail and bail was set at $200,000. She was also booked for a separate “no bail warrant” from the state Department of Corrections, authorities said.

Arraignment for the controlled substance homicide charge took place in Kitsap County Superior Court on Aug. 7 and Doering entered a plea of not guilty. Bail remained at $200,000 and a trial is currently set for Sept. 25.

Mase was found to already be in custody at the Thurston County Jail. Once released, he will be transported to Kitsap County where he will arraigned on the homicide charge, police said. Bail will be set at $250,000. Mase will also face an additional outstanding arrest warrant for possession of a stolen motor vehicle.
