Police said Sunday that an "America's Most Wanted" television show segment about a missing Indiana University student generated at least 30 to 40 tips, but so far none of them have led to major breakthroughs in the case.
Lauren Spierer was last seen walking home alone from a friend's apartment early June 3, a few hours after she left a popular Bloomington bar. The case of the missing 20-year-old student from Greenburgh, N.Y., was featured on "America's Most Wanted" on Saturday. Bloomington police say the show generated 30 to 40 tips between the show's 9 p.m. airing and 3 a.m., but none have led to any breaks in the investigation.
Police Capt. Joe Qualters hoped for more tips Sunday.
Robert Spierer told reporters at a news conference Sunday in Bloomington that twice-a-day searches for his daughter will continue all week. His wife, Charlene Spierer, said she had a message for whoever has Lauren or has harmed her.
"Shame on you," she said. "Shame on you."
She begged anyone with knowledge of what happened to her daughter to come forward and said the family is just looking for answers.
The mother also had a message for her child. She said she wants Lauren to know her mother remains strong and as determined as ever to find her.
"I am here for you 100 percent. I will never leave you," Charlene Spierer said. "I love you with all my heart, and I need you back."
Police have been interviewing people who know Lauren Spierer and have 10 people of interest. They emphasized that those individuals are not suspects.
Investigators have obtained security video from the area where Lauren Spierer was last seen. Qualters said they are not planning to release any of the footage.
He said video evidence last shows Spierer between 3:15 and 3:30 a.m. on June 3 walking. He wouldn't say whether she was alone or what else the video shows.
Police have said Spierer went to a friend's apartment and left to walk home alone around 4:30 a.m., which was the last time anyone saw her.
Qualters said a representative of Texas Equusearch, a national search group, was in Bloomington on Saturday. He said police plan to meet with the group, which provides horse-mounted search and recovery volunteers, to determine if it can provide any services in this case.
