Lt. Andrew Neiman tells the Los Angeles Times ( http://lat.ms/1kckrm2) that 40-year-old Sami Hayek may have been going too fast on a curvy stretch of Sunset Boulevard when he lost control of a high-powered Ford GT Sunday afternoon.
Neiman says the muscle car fishtailed, crossed into oncoming traffic and hit a pickup truck.
The crash broke Hayek's ribs and killed his passenger, photographer and Grammy-winning art director Ian Cuttler Sala.
The pickup driver suffered a broken foot.
Neiman says no drugs or alcohol were involved.
The actress's younger brother is a furniture designer. Efforts to reach him and Salma Hayek were unsuccessful.
According to his website, the 43-year-old Cuttler won a Grammy for his design of the "Johnny Cash: The Legend" music box set.
