A 12-person jury in Los Angeles County convicted Eric Ronald Holder Jr., in the killing of Hussle outside a clothing store the rapper owned in south Los Angeles.
Prosecutors said the 32-year-old shot Hussle at least 10 times when the pair had a chance meeting on a Sunday afternoon in the neighbourhood where they both grew up. After a brief conversation, Holder left and returned about 10 minutes later and opened fire, killing Hussle and wounding two bystanders.
Public defender Aaron Jansen acknowledged that Holder killed Hussle but argued that he should not be convicted of first-degree murder because the attack was not pre-meditated.
Jansen said Holder acted in "the heat of passion" after Hussle told him there were rumours of him "snitching" to police, which he considered a serious offense. Holder did not testify during the trial.
Hussle, who was 33 when he died, had publicly acknowledged that he joined a gang as a teenager. He later became an activist and entrepreneur as he found success with rap music and collaborated with artists including Snoop Dogg and Drake.
In 2020, Hussle won two posthumous Grammy Awards including one for Racks in the Middle, released a few weeks before his death and featuring Roddy Ricch and Hit-Boy.
Deputy District Attorney John McKinney said he hoped the verdict provided "some resounding peace" to Hussle's family and fans and that the rapper's life would inspire others "to get to a place where dreams are made."
Holder also was convicted of attempted voluntary manslaughter for wounding two bystanders in the incident.
Holder could spend the rest of his life in prison. Sentencing was set for September 15.
