Police say it will likely be two weeks at least until tests are concluded on the driver of the car that killed bicyclist Diana Hersevoort on June 9.
The Pleasanton Police Department will forward the results of those tests -- probably blood tests for alcohol or illegal substances -- and the department's examination of the accident scene to the Alameda County District Attorney's Office. It will make the decision if charges will be filed against the young driver.
Hersevoort, 58, and her husband were riding north on Foothill Road when the two were hit by a car, according to police. The accident took place near Golden Eagle Way, at about 1 p.m. Hersevoort, who was thrown from her bicycle, was pronounced dead at the scene.
Her husband Joe was taken to a hospital where he was treated and released with a broken leg.
The car, a 2004 silver Dodge Neon, was driven by an 18-year-old Pleasanton man who was also heading north, police said. The 18-year-old stopped at the scene and answered police questions but did not give a statement, police Sgt. Robert Leong said.
The driver has not been arrested, and the cause of the collision remains under investigation. Preliminary information indicates that Hersevoort and her husband were riding single-file in the bike lane when they were hit.
Leong said several witnesses have contacted police.
Police were at the scene several days following the accident; meanwhile, the scene has become an informal memorial to Hersevoort, with flowers placed along the road near where she was struck.
The bicycle ride was a weekly tradition by the couple, who rode together throughout the Tri-Valley region, said one of the couple's grown daughters, Heather Grimm.
They had been together for 35 years.
Grimm said a private celebration of Hersevoort's life is being planned -- and will take place outdoors because her mother loved nature. No date has been set.
