LOS ANGELES, California - Fans of "Fast & Furious" star Paul Walker have created a makeshift memorial at the site where the actor and a friend were killed in a fiery crash on November 30 2013.The Los Angeles County Sheriff's Department says speed was a factor in the crash in the community of Valencia, 48km north-west of Los Angeles. Deputies found Walker and his friend in the 2005 red Porsche Carrera GT engulfed in flames, the friend apparently the driver.Walker's publicist said the other person in the car was Roger Rodas, a friend of Walker's who owned a sports-car dealership in Valencia.HORROR CRASHThe Porsche crashed into a light pole and tree and burst into flames. The downed light pole had a 45mph (72km/h) speed limit sign attached to it.Sheriff's deputy Peter Gomez said investigators were working to determine how fast the car was going and what caused it to go out of control, including whether the driver was distracted or something in the road prompted him to swerve.Walker and Rodas had attended a fund-raiser for victims of the recent typhoon in the Philippines. The event was held by Walker's 'Reach Out Worldwide', a charity he founded in 2010 to aid victims of natural disasters.The event and a toy drive were at Rodas' custom car shop, Always Evolving. Attendees rushed to the nearby crash to try to put out the flames with fire extinguishers.‘HE WAS DOING WHAT HE LOVED’Bill Townsend, who attended the event, said: "He was smiling at everybody, just tickled that all these people came out to support this charity. He was doing what he loved. He was surrounded by friends, surrounded by cars."The star had been on a break from shooting the seventh instalment of “Fast & Furious”. Universal Productions has not said what it plans to do with the rest of shooting for the movie which is set for release in July 2014.Musician Ludacris, Walker's "Fast & Furious" co-star, said on Twitter: "Your humble spirit was felt from the start. Wherever you blessed your presence you always left a mark, we were like brothers.""Fast & Furious" co-star Vin Diesel posted a photograph of Walker on Instagram with the message: "Brother I will miss you very much. I am absolutely speechless."
