British scientist Dr. Natalie Christopher — who vanished during a morning run on the Greek island of Ikaria — may have been crushed by large rocks after falling into a ravine, according to new reports.

Authorities have confirmed that Christopher’s body was found in a 65-foot-deep ravine not far from where she and her beau, from Cyprus, were staying on the Aegean island of Ikaria, the Evening Standard reported.

She was discovered “lying on her back, crushed by several large rocks,” Greek TV station Skai TV reported Wednesday night.

Rescuers also told ERT TV, another Greek outlet, that Christopher was rock climbing and apparently slipped and fell.

But those theories have yet to be officially confirmed, and Christopher’s autopsy was scheduled for Thursday, according to the Standard.

Christopher’s partner reported her missing Monday when she didn’t answer her phone.

Before heading out for her run, the Oxford-educated scientist told her beau, “I can’t go fast. I’ll be back slowly, don’t worry,” according to Metro UK.

Christopher, originally from London, moved to Nicosia on Cyprus about 11 years ago, according to the Standard.

Since then, she has conducted research at the European University Cyprus in the Astrophysics and High-Performance Computing group, the outlet reported.

Christopher was also at the helm of the “Cyprus Girls Can” campaign, which encouraged women and girls to become more involved in athletic activities, according to the report.

“I express the sincere condolences of the Cypriot state and of myself to the family and friends of Natalie Christopher,” Cypriot Justice and Public Order Minister George Savvides told the Standard.
