A photo of actor Paul Walker is seen December 1, 2013 among flowers and candles left by fans at the site of the car accident in which the "Fast and Furious" actor and another man died the previous day, in Santa Clarita, California.   Santa Clarita police warned fans Monday against "burning rubber" near the spot where the car Walker was a passenger in crashed, as they continued to probe the accident. 
Police issued the caution after reports of people pulling stunt maneuvers on the stretch of road in town northwest of Los Angeles, where Walker died on Saturday.  AFP PHOTO / Robyn Beck        (Photo credit should read ROBYN BECK/AFP via Getty Images)
