Lanez, 29, whose legal name is Daystar Peterson, was handcuffed in a Los Angeles courtroom and taken to jail.
She said that an investigation showed there were four DNA contributors on the handgun, making it inconclusive whether Peterson’s DNA was found.
Peterson, Megan and others were in an SUV in the Hollywood Hills after a party on July 12, 2020.
Megan Thee Stallion was already a major up-and-coming star at the time of the incident, and has thrived since.
