Athens (CNN) A 27-year-old man has confessed to killing US scientist Suzanne Eaton on the Greek island of Crete, a police spokesperson told CNN Monday.

The local man had been detained by police for questioning, after the 59-year-old molecular biologist went missing July 2 while attending a conference.

More details are expected to be announced Tuesday, Crete police said.

Eaton was attending a conference at the Orthodox Academy when she disappeared, apparently during a run.

Last Monday, her body was discovered by two locals deep inside a cave, according to Crete's Chief of Police Konstantinos Lagoudakis.
