Police Search For Rihanna’s Stalker After He Made Death Threats Online

Well, this is scary! Police are investigating another deranged man who mentioned killing Rihanna online.

The stalker, who goes by Alex Mercer on Twitter and Ralph Alexander on Yahoo, took a picture outside the superstar’s former house on April 30th (above) and posted it to Instagram. He followed the photo with the violent tweet, “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.”

Police were called to the home after the tweet, but by then, the perpetrator had left. Reports say authorities are trying to pin down the suspect through social media.

Rihanna has had her share of stalkers. Just last year, Kevin McGlynn, 54, was arrested for sending letters to RiRi’s NYC apartment allegedly threatening her with murder and rape. He was later sent to a psychiatric hospital.
