A woman accused of the attempted murder of Gabriela Spanic, an actor in Mexico, is said to have been slowly poisoning her and her family by adding tiny amounts of ammonium sulphate to their food. The name of the chemical was incorrectly translated from the Mexican police report that actually refers to ammonium sulfide, which is not used in fertilisers, unlike ammonium sulphate, which is, and was referred to in the story below.
Police in Mexico have arrested the personal assistant of one of the country's biggest telenovela stars for attempted murder of her employer, as well as the actor's mother, two-year-old son and maid.
In a statement police said Marcia Celeste Fernández Babio, 24, had been working for actor Gabriela Spanic since January.
