MONTEZUMA, Iowa (AP) — Investigators are planning to give an update on the search for a missing 20-year-old Iowa college student who vanished nearly two weeks ago.

A news conference is scheduled for 1:30 p.m. Tuesday at the Poweshiek County Sheriff’s Office in Montezuma, a community between Des Moines and Iowa City.

The Iowa Division of Criminal Investigation has said that Mollie Tibbetts was last seen jogging in her nearby hometown of Brooklyn on the evening of July 18.

Her family reported her missing the next day after she didn’t show up to work. Since then, local, state and federal investigators have tried to determine what happened.

Thousands of volunteers have aided in the search for Tibbetts, a University of Iowa student who was home for the summer. Family members have said she was dog-sitting at a home where her longtime boyfriend, his brother and the brother’s fiancee live.
