Police said at a news conference late Monday afternoon that they had taken John Robert Charlton into custody in the slaying of Ingrid Lyne, 40, a nurse at Swedish Medical Center.
Police were able to identify Lyne because one of the body parts found in Seattle was her head, according to a law-enforcement source familiar with the investigation.
Homicide detectives learned Saturday that Lyne had been reported missing to Renton police and obtained a photograph they used to tentatively identify her.
Lyne’s friends took to social media over the weekend with concerns about her welfare. They reported that the single mother went on a date in which she planned to attend Friday’s Seattle Mariners game with someone she had met online.
Some of the social-media posts identified Charlton as Lyne’s date. His name and photograph were posted on Facebook, before the announcement of his arrest, by people who identified him as Lyne’s date.
Lyne wasn’t home Saturday morning when her former husband planned to drop their children with her, police said. She was reported missing just after 10 a.m.
Her SUV was initially reported stolen and her cellphone, wallet and other personal items were found at her home in Renton, her friends said. Late Monday, police announced they found the SUV, a silver 2015 Toyota Highlander, in downtown Seattle.
