Following (last below) is an excerpt from a report on the event from "Notiver," a Veracruz, Mexico newspaper.

To summarize some points from the excerpt: Eloy Le ón’s sister-in-law (Gertrudis) believes that his mother was, to some extent, aware of his plans to murder his family and reported to the sister-in-law some days before the crime that she was worried that he would do something crazy/foolish. [Eloy may have suggested as much to his mother in advance.] The mother is currently being held for questioning.
Gertrudis stated that Eloy planed the crimes, evidenced by the fact that on the day before the murders, he took his family to the beach – along with his niece (Luz Marilín) – and, as they were facing the ocean, told his daughters to take a good look at everything and to enjoy those moments because it was for the last time, since it was all vanity/fantasy (Sp. “una fantasía”). The young niece later told her family members that, after her uncle uttered those strange words, her six year-old cousin Luz María (Eloy’s only surviving daughter) asked her what was the meaning of the word “fantasía.”
Gertrudis told the authorities that Eloy mistreated/abused his family, but that no one realized it; she further believes that he was fully aware of his actions (the massacre), because after committing the deeds he telephoned her and told her to come quickly to the house because something terrible had happened.
The report begins by relating (not reprinted below) that Eloy acknowledged suffering mental anguish and torment, and read the Bible for several hours prior to setting about implementing the murders at six o’clock on that Thursday morning.
[“…
Manifestó la señora Gertrudis que unos días antes del crimen la madre de Eloy fue a buscarla a su casa para comentarle que estaba muy preocupada porque presentía que el hombre iba a cometer una tontería, y que esto lo dijo seguramente porque Eloy ya había comentado sus planes.
Gertrudis dijo que a pesar de vivir muy cerca de su hermana Lucía y sus sobrinitas desconocía lo que Eloy las hacía pasar, porque nunca se les separaba. La que sabía todo, es la madre del ahora detenido.
Declaró Gertrudis que Eloy planeó los crímenes porque un día antes las llevó a la playa Chachalacas, también fue con ellos su sobrina Luz Marilín Carmona Varela quien les dijo que estando frente al mar, el hombre les dijo a sus hijas que miraran bien todo y disfrutaran esos momentos porque era la última vez, ya que todo era una fantasía.
La pequeña Luz Marilín dijo a sus familiares que después de que su tío dijo las extrañas palabras su prima Luz María, la de seis años que sobrevivió a la tragedia, le preguntó a ella que qué significaba “fantasía”.
Gertrudis dijo a las autoridades que Eloy León maltraba a sus familiares pero nadie se daba cuenta, por lo que cree que estaba conciente de lo que hacía, pues luego de cometida su acción le llamó por teléfono y le dijo que fuera rápido a su casa porque había ocurrido una desgracia.
