This girl showed no signs of a sucidal person. I bet it was a fanatic towel head for sure (probably a woman based on modus operandi). Also the person to find the body and the last one to see the victim alive are the primary suspects. I don't believe in coincidences, well one coincidence fine, but two? Three if you count the unfriended evidence. That "best" friend most probably did it. Out of envy and with the approval of Islam. Hope the truth comes sooner than later and her family can finally go on after such tragedy.

Why the investigation officer do not consider such important digital evidence? https://mujunaeem.wordpress.com/2017/04/02/the-case-of-the-missing-instagram-users-from-raudha-follow-list/
