One of the grown daughters of a woman who was killed while biking
in Pleasanton with her husband on Sunday afternoon described her mother today
as an animal lover and a "bright, loving person."
Diana Hersevoort, 58, and her husband were riding north on
Foothill Road, near Golden Eagle Way, at about 1 p.m. when the two were hit
by a car, police said.
The car was driven by an 18-year-old Pleasanton man who was also
heading north, police said.
Hersevoort was thrown from her bicycle and pronounced dead at the
scene. Her husband was taken to a hospital where he was treated for minor
injuries and released.
The couple's daughter Heather Grimm, 30, said in a phone interview
from her family's home in Dublin today that the bicycle ride was a weekly
tradition by her parents, who rode together in various parts of the
They had been together for 35 years.
Hersevoort had been a stay-at-home mom to Grimm and her older
sister and was a proud grandmother to Grimm's 7-year-old son and 2-year-old
daughter, Grimm said.
Grimm said her mother loved animals, and that growing up, their
house was a "zoo" with many cats and dogs. The couple still has two cats and
three dogs at their Dublin home.

"The world is a darker place without her," she said.
Grimm said the local community and her extended family are
providing support. A high school friend of her mother's stopped by with five
bags of groceries after the accident, she said.
Grimm said a private celebration of Hersevoort's life is being
planned -- and will take place outdoors because her mother loved nature.
"She was a lover of animals and flowers," Grimm said.
Hersevoort was also a fan of tie-dyed clothing, something Grimm
hopes people will wear to her memorial.
The accident remains under investigation, Pleasanton police Sgt.
Bob Leong said.
The driver has not been arrested, but police said he is not
cooperating with their investigation.
Leong said preliminary information indicates that Hersevoort and
her husband were riding single-file in the bike lane on the side of the
roadway when they were hit.
He said several witnesses have contacted police.
"If we have enough to pursue a charge we will forward it" to the
Alameda County District Attorney's Office, Leong said.
Grimm said her parents were safe and cautious people who followed
the rules of the road while on their mountain bikes.
"What was taken cannot be replaced," Grimm said.
