Woman uses black magic to kill sister, stabs her 68 times

She allegedly committed the murder because she wanted her older sister's husband all to herself.

Shocking new details are being revealed about a murder case from 2016, where a woman hired a witch doctor to curse her sister before murdering her by stabbing her 68 times. 
According to Ary News, the documentary is based on the true story of Sabah Khan, who murdered her older sister Saima in their UK home in May 2016.
She allegedly committed the murder because she wanted her older sister's husband, taxi driver Hafeez Rehman, all to herself after having been in an affair with him for four years.
Sabah lured her sister by saying that her children were crying, before stabbing her to death, chopping off her hand and almost decapitating her by slashing her throat.
Saima's four children aged one to seven, who were asleep upstairs, woke up as the 'scene of carnage unfolded' and Saima's seven-year-old daughter shouted down to her aunt: 'Are you killing a mouse?'
Investigators involved in the documentary trace Sabah's activities before killing her sister, including paying 5,000 pounds (Dh 23,000) to a witch doctor to curse her.
Sabah Khan had been sentenced to life with a minimum term of 22 years in 2017 after pleading guilty to her sister's murder.
