Ivanna Ortiz, the alleged shooter of Rihanna's Los Angeles mansion, has pleaded not guilty to attempted murder and several other felonies. She is accused of spraying AR-15 rounds at the singer's home on March 8 and planning to fire 20 rounds towards a home with children present. The shooting was caught on camera and could have resulted in multiple homicides, according to prosecutor Alexander Bott. Ortiz's bail was denied. The alleged shooter was obsessed with Rihanna and had previously targeted another pop star.
