The 29-year-old North Seattle man accused of killing wine steward Yancy Noll near Lake City Aug. 31 is being held without bond, the Seattle Times reports.
Dinh Bowman faces first or second-degree murder charges, to be filed by Tuesday, according to senior deputy prosecuting attorney Scott O'Toole.
Bowman had not made any statement to police as of Saturday.
Bowman was denied bail because of his extensive attmepts to conceal the crime. He shot through the passenger-side window of his silver BMW Z4 convertible and replaced the glass, changed all four tires, repainted the car's wheels and hid the car.
Bowman, a graduate of the University of Washington with a degree in electrical engineering, is accused of firing five shots at Noll at the intersection of 15th Ave. N.E. and N.E. 75th St. Three shots struck Noll in the side of the head and he died at Harborview Medical Center soon after.
Bowman and Noll, 43, apparently did not know each other, O'Toole said.
Seattle Police arrested Bowman early Friday at his home.
Investigators searched Vague Industries in Sodo, where Bowman works, and found the old tires, as well as masking tape used to paint the wheels, O'Toole said.
The Times reported that Bowman was a child prodigy, taking college-level computer science courses when he was 13 while he was nationally ranked in fencing.
In 2006 he was acquitted of burglary and first-degree theft.
