Lindsey's mother, Melissa Baum, told ABCNews.com that her daughter had gone to the friend's house with her older brother to inquire about a sleepover, but the two had quarreled on the way, so Lindsey continued without him. After being told the friend could not stay the night, Lindsey headed home around 9:30 p.m.
After Lindsey missed her 10 p.m. curfew Melissa Baum set out on foot to try and find her daughter. Lindsey's friends' parents joined the search by car. Baum even let her daughter's beloved German shepherd, Kadence, off its leash in hopes the dog would help find her. Finally, around 10:45 p.m., Baum said she called the police.
Authorities said witnesses were able to put Lindsey within a couple of blocks of her house just after 9:30 p.m. The last person reported to have seen her was a neighbor on her way to work.

The Portland, Ore., second-grader vanished from his elementary school on June 4, shortly after giving a science fair presentation on frogs. While investigators and volunteers initially scoured the neighborhood and dense forest surrounding the school, speculation quickly turned to Kyron's stepmother, Terri Horman.
Though Terri Horman has not been charged or named a person of interest in the case, the boy's biological parents, including Terri Horman's estranged husband have publicly accused her of snatching the boy and then hiding his whereabouts.
As the trail grew cold, the Horman family drama increased. Kaine Horman, Kryon's father, filed for divorce and was granted an emergency restraining order against Terri Horman to keep her away from him and their young daughter after police told him of Terri Horman's alleged plot to hire a gardener to kill him.
More recently, police have sent out new fliers asking the public if they saw Terri Horman and close friend DeDe Spicher with Kyron the morning he disappeared. Spicher, who also has not been charged in the case, has been subpoenaed to testify before a grand jury.

Michelle McMullen, a 27-year-old student from Harrisburg, Pa., has been missing since Sept. 28, 2008 when she left her hometown to return to Grambling State University in Louisiana.
Her father, Michael McMullen, said he is convinced that his daughter was abducted. He said he is frustrated and angry that police and the media are focusing on a warrant for his daughter's arrest.
Michelle McMullen, mother of a little boy, faces charges of theft by unlawful taking, theft by deception and two counts of forgery in connection with the disappearance of $2,000 from the Progress Emmanuel Presbyterian Church, where she worked as an administrator for two years. The money was reported missing after a church audit.
"We're firmly believing one thing has absolutely nothing to do with another," Michael McMullen told ABCNews.com today.
"This girl is not going to walk away from life for $2,000," he said.
Police in Hagerstown, Md., found McMullen's 2002 Honda Accord shortly after she disappeared with her cell phone, wallet and identification inside.
