A Brazilian music producer who was a leading nominee at the Latin Grammys has died after leaving the awards.
Capone's five nominations is believed to be a Brazilian record
Tom Capone, whose real name was Luis Antonio Ferreira Goncalves, was killed in a motorcycle crash in Los Angeles.
The 37-year-old had been nominated in five categories at the awards, including producer of the year and album of the year.
Police said Capone may have run a red light before the crash and his body will be tested for traces of alcohol.
Capone died of "massive head trauma" after his motorcycle collided with a car on a major road, hours after the Latin Grammys ended on Wednesday night.
Police said his bike collided with a car driven by a 23-year-old woman at about 3:30am local time. Capone was pronounced dead at the scene of the accident.
Los Angeles police lieutenant Steve Allen said Capone had been wearing a "novelty helmet" that would have provided little protection.
Lt Allen said Capone may have run a red light before the crash, adding that the woman involved was not injured in the accident and would not be charged.
"Somebody ran a red light," he said. "The only person still alive says she didn't run a red light."
He said the 23-year-old woman passed a breathalyser test at the scene, while an autopsy would seek to determine if Capone was under the influence of alcohol at the time of the crash.
Capone produced award-winning albums for Brazilian singer Maria Rita and the rock band Skank.
His five nominations at Wednesday's Latin Grammys made him the most nominated Brazilian in the history of the awards, according to Billboard magazine.
The magazine said Capone began his career as a guitarist in 1980s band Peter Perfeito, before opening his own studio and turning to producing.
He worked with artists such as Gilberto Gil, Milton Nascimento, Raimundos and Barao Vermelho and had recently produced three tracks for Spanish-language group Bacilos' new album.
However, he was best known for his work on Rita's eponymous debut album, which has sold more than 600,000 copies worldwide.
