At 2:50pm on 31 March last year, the rapper Nipsey Hussle sent out a tweet.
Just 30 minutes later, he was dead.
CCTV footage shows a man approach Nipsey, with a gun in each hand, and open fire on him outside the clothing store he owned in south Crenshaw, Los Angeles.
The man pulled back before returning to shoot him again.
One final time he retreated, before reappearing, shooting Nipsey and kicking him in the head.
The killing horrified fans around the world, with tributes from celebrities including Drake and Rhianna and, very quickly, rumours spread about the murder. In BBC Three's new documentary The Mysterious Murder of Nipsey Hussle, filmmaker Ben Zand speaks to people who knew Nipsey, as well as to LA police and gang members, to investigate the life and death of the world-famous rapper.
Who was Nipsey Hussle?
Rapper Nipsey Hussle - real name Ermias Asghedom - was born in Crenshaw in 1985.
He was regarded as a hero in his community. He owned a record label and the rights to his own music. He clocked 1.8 billion music streams in one year, won two posthumous Grammys and became an icon around the world, thanks in part to his investment in science and tech projects for underprivileged young people.
"A huge part of the reason people felt attached to Nipsey was [his message of], 'Hey, as black people we need to be building our stuff. We shouldn't be so dependent on white entities to survive," says fan and community organiser Chavonne Taylor.
"Also by encouraging us to join him. That's what all of his music was: 'Join me in this. Let's own our communities'."
