Four children die in accidental poisoning in Texas

A criminal investigation is under way into an accidental poisoning involving a professional-grade pesticide that left four children dead and a woman in critical condition, police said.

Authorities are looking into why the family had the pesticide pellets, called Weevil-cide, which is only supposed to be sold to people with professional licences or certification and is marketed for use in rodent control in commercial transport of commodities and animal feed.
