Investigators from the Los Angeles County Sheriff's Department will meet with engineers from Porsche next month to analyze the data retrieval system, the department said. That system could shed light on the car's speed, throttle opening, air bag deployment, seat belt use and possibly other information from the time of the crash. Walker, the 40-year-old star of the "Fast & Furious" franchise, died on November 30 when the 2005 Porsche Carrera GT he was riding in slammed into a pole and burst into flames. Rodas was behind the wheel. The exact cause of the crash remains unclear, but witnesses told authorities the car was speeding near a business park in the Santa Clarita community of Valencia, California. The posted speed limit in the area is 45 mph. A toxicology report, which could show if drugs or alcohol played a role in the accident, won't be available for several more weeks. Walker was attending a holiday toy donation event for his charity, Reach Out WorldWide, on the day of the crash when he hopped into the car with Rodas for a ride, witnesses said. After the crash, Los Angeles authorities arrested a man accused of swiping a piece of the charred Porsche while it was on a tow truck. Thousands of fans across the country mourned Walker's death on social media and at the scene of the crash, where Walker's co-star Tyrese Gibson broke down sobbing as he laid a yellow flower at the site.
