King County arrests woman’s fiance 6 years after her killing
SEATTLE – An investigation by the King County Sheriff’s office and the prosecuting attorney’s cold case unit has led to a second-degree murder charge against a Woodinville woman’s fiance six years after she was found beaten and strangled to death in the trunk of her car.
Sione Lui, 37, was arrested Friday night and booked into King County Jail, said Sheriff’s Sgt. John Urquhart. He is being held on a $2 million bail.
The family of Elaina Boussiascos, 27, told the Seattle Times they were relieved after six years of waiting.
A combination of DNA evidence, contradictory statements and other inconsistencies by the suspect enabled detectives to build their case. Urquhart said Lui had always been a person of interest in the case.
“There was no ‘Eureka’ moment in this case,” Urquhart said. “It was part science, part good police work, all rolled into one.”
Lui was engaged to Boussiacos when she was reported missing in February 2001. Urquhart said Boussiacos had told her family she was going to break off the engagement because Lui was having an affair.
Boussiascos’ son alerted his family that his mother was missing when he called to say she hadn’t arrived to pick him up after school.
Boussiacos’ body was discovered on Feb. 9, 2001, in the trunk of her car outside a Woodinville health club about a half-mile from her home.
A bloodhound led detectives to the duplex where Lui and Boussiacos lived, Urquhart said. It appeared the body had been dressed by someone else, and Lui’s DNA was found on her shoelaces, Urquhart said.
They had dated for about two years before her death. Lui told police he last saw Boussiacos around 11 p.m. on Feb. 2. She had planned to fly to California to visit her mother the next day. He said she was gone when he woke the next morning.
At the time of her death, Boussiacos was working as an executive assistant at a database management firm in Kirkland.
