A two-year-old girl has died after eating a poison-laced cookie that was allegedly thrown to the family’s noisy dog.

Heidy Valeria died after suffering two respiratory arrests in the municipality of Tototlan in the Mexican state of Jalisco on 3rd February.

The young girl ate part of the allegedly poisoned cookie and was taken to a nearby hospital on 1st February.

Council general secretary Epigmenio Carrillo said the cause of the intoxication is still unconfirmed. However, the family pet also suffered the same problem.

According to the news site Telediario, the girl suffered two respiratory arrests while doctors battled to save her life, eventually passing away two days later.

A local resident said: “The truth is, the news has shocked the whole town. In fact, social media erupted when it became known what had happened.”

On social networks, Tototlan residents expressed their shock and claimed the girl had been poisoned by someone targeting the family dog.

Carrillo could not confirm the allegation, and said the authorities would make an announcement as soon as the facts had been established.

However, Carrillo did state that another local child, reportedly six years old, had also been hospitalised due to intoxication from an unidentified substance, although it is still unclear if the minor’s condition is related to the deceased toddler.

Activist and influencer Arturo Islas Allende said: “We lost Valeria, we lost a two-year-old girl, because of some unscrupulous characters who threw poisoned cookies in Tototlan, Jalisco. Those guys should be in jail.”

The authorities have offered their full support to the victim’s family as the investigation continues.
