Nina Kraus, 72, a professor at Northwestern University, went missing on Monday in Evanston, Illinois. The institution, located in the same city, asked for help from the public in locating the neurobiology and otolaryngology professor. Kraus left her home around 9 a.m. on Monday for a walk, before disappearing, Northwestern said in a press release. Kraus was wearing long pants, a windbreaker, and had a dark backpack with her, the institution said. Authorities describe the communications professor as being 5′4” with long silver hair, weighing around 140 pounds. The Evanston Police Department is conducting search efforts for Kraus in coordination with the university’s police. There is no indication of foul play, according to an ABC7 report. Evanston PD, without naming Kraus, announced on Tuesday morning that they would be piloting a drone along the shore of Lake Michigan as part of a missing person investigation. Kraus, who holds a Ph.D from Northwestern, is a “scientist, inventor, and amateur musician,” according to her bio on the university’s website.
