PORT ORCHARD, Wash. — A man and a woman were arrested and charged with homicide after the overdose death of a Port Orchard woman earlier this year.

Larry Mase Jr., 33, of South Kitsap, and Alyssa Doering, 19, of Gig Harbor, have been charged in the drug overdose death of Heather Marion-Santos, 43, of South Kitsap, who died April 30.

Kitsap County sheriff’s detectives said their investigation determined that Doering and Mase provided narcotics to Marion-Santos that resulted in her death.

On Monday, Doering pleaded not guilty to the charge. Bail was set at $200,000.

Mase is in custody in Thurston County. Deputies said Mase would soon be transported to Kitsap County for arraignment.

According to the medical examiner, Marion-Santos’ cause of death was from “chronic and acute IV drug use with acute heroin and methamphetamine intoxication.”

“Following various interviews and analysis of forensic evidence, investigators determined Doering and Mase provided narcotics to Marion-Santos resulting in her death,” authorities wrote in a news release.
