A teenage student in the US has been killed after her boyfriend allegedly gave her a lethal injection in what was reported to be "an attempt to commit suicide together".
Salt Lake City Police (SLCP) were alerted by the University of Utah Police to a suspected suicide or homicide case on Friday morning.
An email sent from a student, 26-year-old Haoyu Wang, to a member of university staff stated that he had given his girlfriend an injection of heroin "to relieve her from suffering" and said that both of them would be found dead by the time someone arrived.
