Cops collect evidence in missing Indiana Univ. student Lauren Spierer case

(CBS/WISH) BLOOMINGTON, Ind. - Bloomington police used a battering ram Tuesday night to break into a room located in the apartment building where Lauren Spierer lived.

Spierer, a 20-year-old Indiana University sophomore, was last seen early Friday morning as she left a friend's apartment and started walking home. Her disappearance has sparked a massive search and social media efforts to find her.

According to CBS affiliate WISH, police were serving a search warrant at Smallwood Plaza apartments. Once inside, authorities removed three computer hard drives from the apartment complex's security room, but would not say why. Police could not get someone from the apartment complex to let them into the room.

Police have interviewed Lauren's friends and say they fully cooperated with the investigation.

Investigators say they have few leads and no suspects but believe foul play is to blame.

Her parents made an emotional plea Tuesday for continued help and information.

"There's a lot more that we have to do until we find Lauren. We beg you if you can help us with the search that you continue to join us every day," her father Robert said. "We ask that if anyone saw Lauren on Thursday, Thursday night with anyone, please share that information with the Bloomington Police."
