27 year old man poisoned grandparents and aunt 



Yesterday, thursday, the Italian police confirmed the arrest of a 27-year old man who used thallium, used in rat poison, to murder his grandparents and an aunt because he claimed they were “unclean”.

The prosecutor, Maria Luisa Zanetti, told reporters that 27-year-old man named Mattia Del Zotto said he killed his family and used the poison on another five relatives “to punish unclean people”.  Del Zotto bought the thallium from a company in Padua near Venice, and sprinkled the toxic chemical in the drinks and dishes of his family members.  

His paternal grandparents, aged 94 and 88, and a 62-year-old aunt died in October after ingesting the poison at the start of October. He then tried to poison other relatives. Five others, including his maternal grandparents, who have been hospitalised in the past weeks.

The police were able to apprehend del Zotto thanks to an email on his computer quoting the poison’s price as well as tax and shipping rates, investigators said. His mother told investigators del Zotto had become “manic”. He spent his days in front of his computer and had stopped eating sweets and drinking alcohol, saying people were only allowed to consume “vital” things.

Thallium, a soft metal, has long been used as a murder weapon as it dissolves in water and is odourless and tasteless.
