A young Danville web designer may have been speeding along Crow Canyon Road before the head-on collision that claimed his life Sunday afternoon, authorities say.
Medical personnel pronounced Geoffrey Mapplebeck, 25, dead at the scene after he crashed his Saab, which was headed southbound, into an oncoming Subaru Forester about a mile north of Norris Canyon Road around 4 p.m. Sunday, according to the California Highway Patrol.
The Subaru's driver and lone occupant, a 61-year-old Castro Valley resident, suffered a broken leg in the wreck, according to the CHP.
The incident remains under investigation, but authorities think Mapplebeck may have been speeding.
A 2011 graduate of Ex'pression College for Digital Arts in Emeryville, Mapplebeck was the creator of a website-design firm and search engine team in Danville, eWebsiteServices. The group's website memorializes the 25-year-old on its home page.
Mapplebeck graduated from San Ramon Valley High School in 2007, according to his Facebook account.
