The Hilux was at fault (wrong side of the road and overspeeding). Guards here (in karachi) mostly use single cabin. Double cabins like this mostly used by officers or their ofsprings or drivers. I could be wrong here, BUT The people inside the car were no guards.
I cannot. But the guy was almost dead and I don't trust the police walas. And a body is found nearby (seaview and gizri, dha aren't VERY far apart). Dates also match. I just think it could be one lead the authorities could take up. I have no proof nor its my job to investigate. I reported what I saw.
