When Francia Ruth Ibarra Ramirez failed to show up after agreeing to meet her friends at the movies, they feared something was wrong.
Her mobile phone had been turned off, so they searched through the 26-year-old's student's social media accounts and informed police that she had been dating former student Emmanuel Delani Valdés Bocangegra after meeting him on the dating app Tinder, debate.com.mx reports.
Ramirez had never introduced Bocangegra to them and he reportedly avoided meeting her friends and family.
Ramirez, from the city of León in Guanajuato, Mexico, had dated Bocangegra, also 26, several times before she disappeared on December 3.
