Juana Barraza

She was nicknamed “La Mataviejitas,” or “the Old Lady Killer,” and was sentenced to 759 years in prison for 11 charges of murder. They discovered numerous elderly women strangled in Mexico City in the early 2000s and discovered they were Juana’s victims.

She pretended to be a government employee and knocked on their doors. Barraza would assault and strangle her victims with phone lines or garments once she had acquired their trust.

Her acts, according to experts, were the result of her drunken mother, who sold her to a man for three beers. She was molested by the same man when she was just 13 years old.
