In a strange turn of events, the husband of the Pakistani woman who was stoned to death on Tuesday had strangled his first wife six years earlier, according to AFP.

Mohammad Iqbal, 45, told AFP on Thursday that he had killed his first wife because he was in love with Farzana Parveen, the woman whose family stoned her to death.

“I was in love with Farzana and killed my first wife because of this love," Iqbal said.

The reason Iqbal was not in jail for the murder was because he did it in the name of “honor,” and because his son forgave him he wasn’t sentenced to prison.

Under Pakistan's penal code, the family of the victim is allowed to forgive the perpetrator, allowing them to be absolved, according to the Human Rights Commission of Pakistan. With “honor killings,” the victim's family is most likely related to the perpetrator, thus allowing them to go unpunished.

Also on Thursday, Pakistan Prime Minister Nawaz Sharif demanded “immediate action” over Parveen’s death. He instructed his brother, Shahbaz Sharif, the Punjab chief minister, to respond to the "brutal killing of lady in the premises of high court in the presence of police," according to a statement from his office obtained by AFP.

"This crime is totally unacceptable and must be dealt with in accordance with law promptly,” Nawaz Sharif said.

Parveen was three months pregnant when she was killed by her family. Iqbal said she was killed because he didn’t pay her family a large enough dowry.
