He rushed to PIMS, where medics told him that his mother had already expired while his father, Ikhlaq, was being treated for his critical injuries.Usama told the police that his cousin Sahkeel Ahmed was on the wheel when the accident happened.

The deadly incident had strained ties between Washington and Islamabad. Davis went scot-free after paying blood money to the families of the victims.With additional input from agencies.
