WARSAW, Poland -- Poland's prosecutors say they are pursuing murder suspicions in the mysterious death of a young Polish woman vacationing in Egypt.

The April 30 death of 27-year-old Magdalena Zuk has shocked the nation. Footage of her struggling against men in a hospital corridor, and her terrified pleas over the phone to her boyfriend to take her home, have been circulating online.

Head of the investigating team Ewa Weglarowicz-Makowska told a news conference Tuesday they are pursuing suspicions of murder. Other scenarios include a nervous breakdown or human trafficking.
