According to police, Erandy Elizabeth Gutierrez, 16, allegedly stabbed 16-year-old Anel Baez 65 times during a fatal attack on March 19.
Authorities believe that Gutierrez wanted to get back at Baez for posting the "humiliating" photos. When Baez asked Gutierrez to come to her home in Guamúchil in an effort to mend fences, her “sister” allegedly went to use the bathroom but instead grabbed a kitchen knife and carried out the killing.
Gutierrez had been using Twitter to make threats to Baez prior to the alleged murder, according to Notus. "It may seem that I am very calm, but in my head I have killed you at least three times," Gutierrez allegedly wrote on a now-deleted account.
After the deed was done, she allegedly wrote, “I am an [expletive]" and "OMG I did" (sic). The Twitter account was deleted March 21.
She initially escaped, but was arrested while attending Baez's funeral and is expected to be charged with murder later this week.
If convicted, Gutierrez may only have to serve seven years in jail because she is considered to be a juvenile under Mexican law, the New York Daily News reports.
