Walker and Rodas had thrown a fundraiser benefiting victims of the recent typhoon in the Philippines. The event was held by Reach Out Worldwide, a charity Walker founded in 2010 to aid victims of natural disasters.
The fundraiser and toy drive took place at Rodas' custom car shop, Always Evolving, in an area of warehouses and office parks. Rodas, 38, and Walker co-owned an auto racing team.
Rodas competed in 10 Pirelli World Challenge GTS races this year, the racing organization said in a statement.
