Do you have a Taurus in your life? Well, you might want to watch out...
David Jester has spent the last two years looking into whether your star sign really does determine your personal characteristics, or if it's just a fluke?
From his research, David concluded that it does have an impact on whether you turn out as a serial killer or not.
He found that most serial killers were born under the Taurus star sign, which is between April 20 and May 20.
Also, the two particular dates of the year that the most serial killers were born on are April 21, and February 18.
So if you know anyone with those birthdays, we've warned ya!
Notorious killers born in the month included Levi Bellfield, Albert Fish, Steve Wright, and Martha Beck.
