The Florida woman who allegedly shot at the Los Angeles mansion of pop superstar Rihanna has pleaded not guilty to attempted murder and more than a dozen related charges. Ivanna Lisette Ortiz, 35, is accused of trying to kill Rihanna after allegedly firing a semiautomatic rifle at the musician's Beverly Crest mansion at 13:15 local time (21:15 GMT) on March 8. Court documents allege Ortiz was trying to shoot Rihanna, rapper A$AP Rocky, their three young children and others who were in the home and another adjacent property. No one was injured. Ortiz remains in detention and entered her plea on Wednesday in Los Angeles County Superior Court through her attorney. She could face a life sentence. Her attorney sought to reduce her bail, currently set at $1.875 million (£1.4 million), but prosecutors argued that Ortiz fired approximately 20 rounds from an AR-style weapon, endangering lives. Furthermore, the DA's office noted Ortiz allegedly had a wig with her, which suggested premeditation. If convicted, Ortiz faces multiple other charges including 10 felony counts of assault with a semiautomatic firearm and three felony counts of shooting at an inhabited dwelling or camper, with each count connected to individuals she allegedly fired at, including Rihanna and A$AP Rocky's real names, Robyn Fenty and Rakim Mayers, along with their children. Ortiz was reportedly seen driving up to the house and shooting before fleeing. Her vehicle was found about eight miles away.
