A 5-year-old girl who fell overboard off a Disney cruise ship reportedly fell backward through a porthole. The investigation is continuing into the incident that happened June 29 as the ship was returning to Fort Lauderdale after a four-day cruise.

On Sunday, June 29, an unidentified 37-year-old dad leapt overboard to rescue his 5-year-old daughter after she fell from the cruise ship's fourth floor. After finding her in the ocean, he kept her afloat until a small boat manned by crew members was able to retrieve them from the water.

The 5-year-old fell overboard when she lost her balance while sitting on a railing and dropped backwards down a porthole, BSO said.
