Physician suspected of 'horrific' slayings of partner, toddler son

A physician found bloody and semiconscious in a First Hill apartment has been ordered held in connection with the slayings of his partner and their toddler son. A King County District Court judge on Saturday determined there was probable cause to hold Louis C. Chen, MD, in custody on investigation of two counts of aggravated murder in the double homicide. Chen remained hospitalized Saturday at Harborview Medical Center. Dan Donohoe, spokesman for the King County Prosecuting Attorney's Office, said the judge made the ruling by telephone after reviewing an emailed copy of the document of probable cause prepared by police and prosecutors. A document of probable cause outlines the law-enforcement case against the accused. Donohoe said the document of probable cause will be released today. The deadline for filing charges against Chen is Tuesday, Donohoe said. Chen, 39, who was scheduled to begin work this week as an endocrinologist at Virginia Mason Medical Center, was found bloody and semiconscious in his apartment on Seattle's First Hill Thursday morning.
