February 9th Killer

The February 9th Killer is the nickname given to the suspected murderer of Sonia Mejia and her unborn baby, and Damiana Castillo in Salt Lake City in 2006 and 2008, respectively. The murders were committed on the same day, two years apart. Mejia was sexually assaulted and strangled, but her case was never solved. Castillo was also strangled to death, but leads dried up and the investigations went dormant.
However, in 2009, the Utah Crime Lab connected the two murders through DNA evidence. Unfortunately, the man’s DNA doesn’t match any DNA markers already on file with authorities. Police working the investigation released a profile of the suspect, believing him to be Latino, medium built, and at the time of the murders, he was probably a very young adult or even a teenager.
In 2011, the authorities classified the case as cold and the hunt for this psychopath continues.
