A mafia informant who disappeared nearly a year ago was tortured and her body dissolved in acid by her former partner and other family members angry that she had cooperated with authorities, Italian police have said.

According to The Telegraph, the woman, 35-year old Lea Garofalo, was forced onto a truck carrying 50 liters of acid, interrogated by her abductors and later killed in a field near Milan in the night between November 24 and November 25, 2009, investigators said.
