Police officers have searched a wooded area near a highway north of Bloomington without finding any signs of an Indiana University student last seen more than two weeks ago.

That search happened on Sunday as investigators continued looking for 20-year-old Lauren Spierer in and around Bloomington. The Herald-Times reports officers went to the spot in southern Morgan County near the Indiana 37 highway following a tip about a suspicious odor.

Bloomington Police Capt. Joe Qualters says nothing was found related to the disappearance of the Greenburgh, N.Y., woman, who hasn't been seen since about 4:30 a.m. June 3 as she was walking alone to her apartment.

Investigators on Sunday found a 2-foot by 4-foot pile of fresh dirt that might have been left by recent utility work.

Spierer, a fashion merchandising major, had just completed her sophomore year at the school. Her shoes and cell phone were found at a popular sports bar where she was partying in the early morning hours of June 3 with friends. Her keys were reportedly found on a railing near her apartment in downtown Bloomington.

Police last week released an image of Spierer leaving her Smallwood apartment complex in downtown Bloomington, wearing a white v-neck shirt and black leggings. They also released two security camera images of a white truck seen in the area at the time of Spierer's disappearance.

Authorities have described the truck as a mid-2000s shortbed four-door Chevrolet Silverado or Colorado. Police said the images show writing on the back doors and rear panels, but investigators haven't been able to read it. The truck is also described to have distinctive wheels and a short bed liner with possible equipment in the back.

Anyone with information on the vehicle or owner is urged to contact the Bloomington Police Department at (812) 339-4477 or by email at policetips@bloomington.in.gov.
