Police say the teen was busted after the half-naked body of Japie Sass, 49, was discovered in his home in Dullah Omar Street in Fisantekraal on Monday.
The girl, known as a tomboy in the community, was arrested on Tuesday.
Bettie Williams, 62, was the one who found her husband’s bloody body. He was knifed.
“We have been separated for three years, and Japie lived alone, but we never forgot about each other,” a sad Bettie says.
“I found him naked with only a T-shirt on.
“He was a joker and always teased people.
“Everyone who knew him knows that at 7am in the morning, Japie comes outside to sit and watch people.
“He was sickly and when he didn’t come outside on Monday, we thought he was ill.”
“Our daughter Jane Mokave and I found his body in the house, he was naked and full of blood, and he was lying on his bed.”
Janene says they broke open the door.
Sergeant Noloyiso Rwexana confirmed the arrest.
