Paul Walker's tragic death on Saturday, Nov. 30, 2013 has left a lot of people shocked and reeling from the sad news which was so sudden and unexpected, especially because it happened after Thanksgiving and before the start of December. Walker was part of the hugely successful film franchise "Fast and Furious," along with costars Vin Diesel, Jordana Brewster, Ludacris, Michelle Rodriguez, Dwayne "The Rock"' Johnson and Tyrese Gibson.

Walker and his businessman friend Roger Rodas of Always Evolving, died instantly when the car that they were riding, Rodas' red 2005 Porsche Carrera GT, hit a tree and a light pole and then burst into flames in Santa Clarita, California. Rodas was reportedly driving his vehicle and Walker was sitting on the passenger seat beside him. Rodas was said to have lost control of the Porsche that's why they got into the accident. No word yet whether or not Rodas was intoxicated during the accident but it is reported that they were driving fast.
