Investigators hope new clues in the disappearance of a woman who went hiking in Hawaii will help them piece together the moments before she mysteriously vanished.

Amanda Eller, 35, was last seen at the Makawao Forest Reserve Wednesday. 

Family members believed Eller arrived sometime around 7:30 a.m., but a Mother's Day gift Eller's mom received Tuesday, from her daughter, suggests a different timeline of events.

The shipment was dropped off at a local post office in Maui around 10:19 a.m., leading family members to believe Eller didn't arrive at the forest reserve until after 10:30 a.m.

"She's been prepared for this," said John Eller, her father, who described his daughter as a strong, self-disciplined woman who loved to explore nature.

Family and friends have not given up the search after Hawaii-based rescue officials reached their 72-hour search limit and stopped looking. 

Investigators found Eller's car outside the forest reserve, including her cell-phone and keys. Friends said it didn't surprise them since Eller was known to exercise without distractions.

The former Tampa resident moved to Hawaii in 2015. While in the Bay Area she was an occupational therapist and yoga instructor.

Police are investigating multiple possibilities surrounding Eller's disappearance, including foul play. However, Eller's family and friends are hopeful for a safe return.
