LAPD is now on the case of a man who has been stalking Rihanna. A man named that goes by both Ralph Alexander and Alex Mercer on his social media accounts was outside of Rihannas house on April 30th and took a selfie of himself in front of it. The very next day the same guy posted a threat to Rihanna on Twitter and tagged her in it. “Should of killed @Rihanna a minute back I would be good right now. Sorcery is a weapon I use guns, bout to get a gun license, can’t use my hands,” The LAPD are now tracking the man and are hoping to catch him before he goes too far.
