A Mexican teen is in police custody after it was discovered she stabbed her best friend to death after the girl posted naked selfies of them together on Facebook.

Erandy Elizabeth Gutierrez, 16, allegedly stabbed Anel Baez, 16, 65 times in the March 19 attack. She fled the scene, but was arrested when she attended Baez’s funeral several days later.

According to the NY Daily News:

Cops believe she wanted revenge for the “humiliating” uploading of the revealing snaps.

Baez asked her former pal – who she had previously referred to as being her “sister” – over to her Guamúchil, Sinaloa state, home to try and patch things up, according to Mexican media reports.

When Gutierrez arrived she reportedly asked to use the bathroom – but then grabbed a knife from the kitchen and allegedly used it to repeatedly stab Baez.

Police say weeks before Gutierrez invited Baez to her home, she had threatened her former pal on Twitter.

“It may seem that I am very calm, but in my head I have killed you at least three times,” she wrote on a now-deleted account.

Gutierrez will be charged with murder but under Mexican law, can only be prosecuted as a juvenile.

She faces seven years in prison if convicted.
