Preliminary autopsy results indicate a Texas woman found dead in her room on a cruise ship had no sign of trauma.
The investigation continues into the death of 32-year-old Kipi Holcomb of Brazoria County.
Holcomb on Feb. 15 was discovered dead after the Carnival cruise ship Ecstasy left its home port of Galveston.
The Galveston County Medical Examiner's Office did an autopsy when the ship returned to port. Spokesman John Florence says there was no evidence of trauma in an initial look.
Florence says toxicology results should be available next month.
The FBI also has said there was no evidence of foul play.
