The news definitely shakes one's faith in mankind. This pair of 70 year olds befriended homeless men from the streets, housed them, cared for them AND bought life insurance for them. 2 years later, the old women ran the men over and collected insurance payouts as fiancee and cousin.

After the second murder, police became suspicious when the same women turned up to claim payouts. They compared injuries and circumstances for both murders, leading ot the arrest of the pair of ruthless con-women. In lieu of their age, the judge sentenced them to life. Details here.

Think the old lady in the street is harmless? Think again.
