A witness just testified to seeing her 17-year-old sister murdered by their parents after a fight over the teen’s Western lifestyle.

Alesha Ahmed, now 22, recounted a horrific childhood scene where she saw her parents suffocate her sister, Shafilea Ahmed in 2003. The parents allegedly put their hands over their daughter’s face to close her airways while forcing a bag into her mouth.

“They both started hitting her. She was scared as usual,” Alesha recounted in between sobs. “I can’t remember which one grabbed a bag, just a plastic bag, which they put in her mouth and put their hands over her – both of them.”

“She was just gasping for air. She wet herself because she was struggling so much.” She recounted her final moments, “That was it, as if she was gone.”

The fight was a culmination of one year’s worth of arguments about their daughter’s non-traditional lifestyle where the parents believed their girl dishonored the family’s heritage by her Western attire and her boyfriends.

“Shafilea was leading a life she thought our parents would not approve of … There would be physical abuse directed at Shafilea. It was both of them. My mum more because she was at home more,” Alesha recounted.

“There was an incident in the kitchen, she had her hair in a plait and my parents had a knife to scare her. They passed the knife between them. I was in the kitchen then ran off,” she also added. “They were just hitting her. It was frantic and out of control and she just sat there taking it. The knife was used to scare her. After I saw she had marks on her neck.”

Alesha Ahmed did not tell police that she had witnessed her sister’s death until 2010, after she was arrested over a robbery at her parents’ house.

With her testimony comes damning evidence from a police listening device that was planted after the teen went missing in 2003.

Mom Farzana Ahmed was heard telling the family, “If the slightest thing comes out of your mouth, we will be stuck in real trouble. Remember that.”

“By getting the support of newspapers, you can get away with murder,” her dad Iftikhar Ahmed added.

Shafilea’s body was found beside the River Kent in England in February 2004.

For now, the trial over Shafilea’s death continues as prosecutors decide whether Alesha is telling the truth or an elaborate lie.
