Janjira Jeffrey Smith, 51, was charged Thursday in King County Superior Court with first-degree murder in the death of Roger Lewis, 56, and first-degree assault in a stroke that temporarily blinded Thanyarat O. "Nina" Sengpharaghanh, 42, both from insecticide that had been added to a bottle of liqueur.

Smith, who formerly lived in Redmond, is believed to have gone to her native country of Thailand, officials in the U.S. Marshals Service said.

Lewis, who lived at his woodworking business in Redmond after going through a divorce, had an 18-month relationship with Smith but recently told her he planned to marry a woman he had met on a trip to the Philippines, according to court documents filed by prosecutors.

"Smith reportedly did not receive this news well," Kirkland police wrote in an affidavit.

Detectives interviewed Smith, who told them she had a bottle of Jagermeister liqueur at her home that she had purchased for Lewis. She said she had a man, who she met in a bank parking lot, deliver the bottle to Sengpharaghanh.

According to court documents, Sengpharaghanh said Smith told her to make sure Lewis drank some of the liqueur before they went to dinner.

Lewis drank a full glass and Sengpharaghanh drank half a glass, according to the court filings.

Sengpharaghanh told investigators she "almost immediately" felt ill, lost her sight and blacked out. A friend found Lewis dead on the floor of the condo Oct. 7, and Sengpharaghanh, disoriented and blind, was taken to Evergreen Hospital, where doctors found she was suffering from a stroke.

Tests at a State Patrol laboratory showed the insecticide methomyl in the liqueur bottle and the two glasses, prosecutors wrote.
