Bloomington police released surveillance photos showing missing IU student Lauren Spierer and a vehicle of interest. After receiving assistance from the FBI, Bloomington police released the enhanced three photographs during a news conference Wednesday morning.

The first photograph is from the hallway of the Smallwood Plaza apartment building where the 20-year-old IU student lives. It was taken a couple hours before Spierer disappeared and shows her wearing a white top and black slacks.

Two more photographs were released from surveillance cameras on an apartment building at 10th and Morton streets in downtown Bloomington, roughly a block south of where Spierer was last seen at 4:30 a.m. on Friday, June 3rd. That video shows a pickup truck making two laps around the block at 4:14 and 4:24 a.m. The truck is described as a four-door, white Chevrolet full-size Silverado or mid-size Colorado with writing or logos on the sides and possibly the rear quarter panel. Police said the truck may have had equipment in its short bed. The bed had a liner. The truck may also have distinctive wheels. According to dealers, the model is from the mid 2000s. Police have been checking with construction companies and patroling construction areas to see if the truck possibly belonged to one of the companies.

"We're talking a very close proximity where Lauren was last seen in that she was last seen at 11th and College and we basically have this vehicle in the same area twice," said Bloomington Police Captain Joe Qualters. "That person may have some direct responsibility for the event or that individual has information that could lead us to the direction."

Qualters said his officers have not run into any roadblocks in their attempts to speak with persons of interest or witnesses in the case. Fox59 News has learned that one prime person of interest who was among the last people to see Spierer before she vanished has passed a polygraph test.

Lauren's parents and police continued to stress that anyone with information, no matter how little, should immediately contact the Bloomington Police Department at 812-339-4477.
