The brutal murder of a 16-year-old girl by her best friend has shocked local residents in northwestern Mexico, a region plagued by drug and gang related violence.<br /> <br />Facebook posts between the two 16-year-old classmates show the two had become very close friends, but the two had a serious falling out after one of the pair, Anel Baez, posted a picture of her friend Erandy Elizabeth Gutierrez in a 'compromising position' with a boy. <br /><br />The two girls fought bitterly over the photo incident, but finally, Anel Baez invited her friend over to her home in an attempt to patch things up. <br /><br />But, shortly after entering Baez's bedroom, Gutierrez asked to use the bathroom...but instead grabbed a knife from the kitchen and fatally stabbed her ex-friend a reported 65 times. <br /><br />Pretending to be heartbroken over her friend's death, Gutierrez attended Baez's funeral...but by that time, cops had cracked the case, and the murderer was arrested during the funeral service.<br /><br />As a minor, Gutierrez faces just seven years behind bars, but the family of deceased is pushing authorities to treat the killer as an adult, arguing that the 16 year-old should be held responsible for her heinous actions.
