Los Angeles authorities don’t suspect drugs and alcohol contributed to a fatal crash involving Salma Hayek’s younger brother.

Sami Hayek, 40, was injured and a friend was killed in the wreck, shortly before 5 p.m. Sunday in the affluent Bel Air section of West L.A. Law enforcement sources told Radar Online that speed was the likely cause of the accident. Hayek lost control of his 2006 Ford GT as he drove east on Sunset Boulevard. The vehicle crossed into westbound traffic, causing him to careen into a 2011 Toyota Tacoma pickup truck.

Art director Ian Cuttler Sala was pronounced dead at the scene, reports E! News. The 43-year-old Grammy-winning art director was a passenger in Hayek’s two-seater. Hayek suffered several broken ribs and a laceration to his head. Alvin Gomez, 20, the driver of the Toyota Tacoma, suffered a broken foot and complained of pain throughout his body. Both of the men were treated at a hospital.

“Drugs and alcohol weren’t detected on Mr. Hayek at the scene of the crash,” Los Angeles Police Detective Zachary Hutchins told Radar. “Toxicology tests are pending, but it doesn’t appear that drugs/alcohol were contributing factors. Speed does appear to be a contributing factor to the accident. Mr. Sala was wearing his seatbelt.”

According to the police report, Hayek was not arrested. Following the completion of Sala's autopsy, the case will be presented to the district attorney for investigation.
