If you're interested, here are the tapes to Kobe's flight which include the radar of just his flight and audio with ATC. They were N72EX a Sirkorsky S76B helicopter. They departed Santa Ana (John Wayne Airport) and were following the 101 and was getting flight following service from Burbank Tower and then Van Nuys Tower. Normal VFR (Visual Flight Rules) is 3 miles visibility and 500' feet below clouds, this helicopter was operating under special VFR, which meant he only needed to be clear of clouds and 1 miles visibility. I believe they gave him a restriction to maintain at or below 2500 because of airport traffic and I think he crashed at 2400'. It looks more and more like weather was the cause and a pilot encountering IFR (Instrument Flight Rules) conditions.
