An American scientist vanished while attending a conference in Greece last week — and her family fears she may have fallen while jogging on one of the tourist area’s picturesque cliffs.

Suzanne Eaton — a molecular biologist at the Max Planck Institute in Dresden, Germany — hasn’t been heard from since Tuesday, when she was last seen near Chania on the island of Crete.

The 59-year-old missed a 6 p.m. session Tuesday at the conference, where colleagues initially assumed she was preparing for her talk, according to a Facebook page dedicated to her disappearance.

“The next day, she was also not seen at the morning session, but it didn’t become apparent that something was really odd until she missed an afternoon cycling appointment with a friend,” the “Searching for Suzanne” page said. “By dinner time, her colleagues realized that nobody had seen Suzanne in 24 hours, and they began to raise the alarm.”

Her family said they believe the mom of two may have disappeared on a run between 3 p.m. and 5 p.m. Tuesday.

The scientist’s niece, Callie Broaddus, said her phone was left in her room and her running shoes were nowhere to be found, according to the Greek Reporter.

“Due to the rough terrain and extreme heat, we believe the most likely possibility is that Suzanne may have either become overheated and looked for shade or that she may have fallen. We need as many volunteers as possible to help check ravines, trail edges, and under brush and shady areas,” the “Searching for Suzanne” page said.
