India, Sept. 1 -- Southwest Airlines flight attendant Jenny Lupton had a joyous night before she tragically died. She danced with a friend, got a tattoo she was excited about, texted her sister about the tattoo, and hours later, she passed away under "unusual circumstances," her nephew Samuel Lupton told HindustanTimes.com.

Jenny, 50, was found dead at a hotel in Waikiki on August 20. Hawaiian authorities told her family that she died from an apparent fall.

The Honolulu Police Department's investigation is underway. A local medical examiner said her official cause and manner of death have yet to be determined.

The medical examiner in Honolulu called Jenny's sister, Tresa Lupton, and informed her that Jenny was dead, Samuel revealed.
