Zahra Baker

Zahra Baker, 10, was reported missing from her Hickory, N.C., home on Oct. 9, but police have not been able to find anyone outside the girl's immediate family who has seen her in weeks. The girl lost her left leg and hearing in a childhood battle with cancer.

Zahra's stepmother, Elisa Baker, was arrested on unrelated charges and later admitted to writing a ransom note demanding $1 million in connection with the case.

On Oct. 12, Hickory police chief Tom Adkins struggled to keep his composure when he announced that he was canceling the Amber Alert for Zahra and turning the investigation into a homicide case.

But police are still seeking the public's help.

Asha Degree

Ten years ago, on Valentine's Day, North Carolina 9-year-old Asha Davis disappeared.

Her father last saw her asleep in bed at 2:30 a.m. Then a motorist claims to have spotted her on the road outside at 4 a.m.

"There's no clues," Asha's mother Iquilla Degree said. "There's nothing."

Police said they believe Asha simply packed her backpack and started off down the road in the middle of the night. Several motorists past her, but no one stopped to check on her. Eighteen months later, Asha's book bag was found, wrapped in trash bags -- 26 miles away. But still no sign of Asha.

Susan Powell

The 28-year-old Utah mother has been missing since Dec. 7, the day after her husband Joshua Powell loaded up the couple's two young sons on a late night camping trip. West Valley City police say her purse and wallet were left at home.

Police have named Joshua Powell a person of interest in the case and many have expressed skepticism about his story of camping in the freezing Utah woods. Powell hired Salt Lake City criminal defense attorney Scott C. Williams, who most recently represented Elizabeth Smart's accused kidnapper, Wanda Barzee.

Friends and family say Powell was a devoted mother and would never have willingly left her children. The couple was known to have had marital and financial problems, but those who knew them say they had been working out their differences and had seemed happier in recent months.

"I'm trying to stay busy and not think about it," Kiirsi Hellewell, Susan Powell's best friend, told ABC News. "But I don't see how there's any way she can still be alive."

Lindsey Baum

The disappearance of 10-year-old Lindsey Baum has shaken her McClearly, Wash., community.

The sixth-grader disappeared the evening of June 26 as she walked home from a friend's house around 10 p.m. It was a 10-minute walk along a densely populated suburban street.

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.

Kyron Horman

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

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.

Nancy Moyer

Moyer, a longtime financial analyst with the Washington state Department of Ecology, vanished March 6 from her Tenino, Wash., home, leaving two children and a family frantic with worry.

Moyer, 36, was reported missing by her husband, from whom she was separated, when he came to her home to drop off their children. The door to the house was left ajar, the television was still on and a half-finished glass of wine sat on the table.

Thurston County Sheriff's Lt. Chris Mealy said the evidence had him leaning toward the likelihood of foul play, though they were investigating all possibilities.

"I think something happened to her somewhere," he said Monday. "What we're basically doing is conducting a homicide investigation without the body."

Moyer's purse, driver's license, credit cards, clothing and toiletries were all found at the house, and her car was parked in the driveway.

"I think someone took her from her home," Moyer's sister, Sharon Wilbur, said Monday. "She would never leave her kids and run off on her own. That's not her."

Kristi Cornwell

Kristi Cornwell was out for a routine evening walk when she disappeared Aug. 11 a short distance from her Blairsville, Ga. home.

The 28-year-old mother was on her cell phone with her boyfriend, Douglas Davis, when she went out around 9 p.m. Davis told the police that Cornwell said a car was approaching her. He then heard sounds of a struggle. Cornwell yelled, "Don't take me!" Then Davis lost reception.

Police say they believe a man who attempted to abduct another woman on Aug. 2 in Ranger, N.C. -- approximately 25 miles from where Cornwell was last seen – may be involved in Cornwell's disappeareance.

"The timing and the vehicle description involved in this incident indicates a possible connection to Kristi's disappearance," the Georgia Bureau of Investigation said in a statement.

But the man was apparently scared off when another car approached the area. The woman, who did not immediately report the incident, did so only after hearing about Cornwell's disappearance.

Based on the woman's description, the suspect is believed to be a white male in his mid-20s with dark hair. He may be driving a silver, late-model Nissan Xterra with tinted windows and a brush guard on the front.

Cornwell's family said they are still hopeful their daughter will be brought home safely.

"Her son needs his mother back, and I need my baby back," her mother, Jo Ann Cornwell, said tearfully. "And we believe we're going to get her back."

Her mother and boyfriend spent weeks in South Carolina, posting flyers and scouring nightclubs in hopes someone had information.

The group of men she was visiting the night she disappeared were questioned and returned home. No one has been charged in her disappeareance.

"It could range the whole gamut from 'I'm a runaway' to 'I've been abducted and killed,'" said Myrtle Beach Police Capt. David Knipes.

Robert Wiles

Robert Wiles was 26 years old when he disappeared on April 1, 2008 from his family's aviation business at the Lakeland Linder Regional Airport outside Tampa.

The FBI says it believes Wiles was kidnapped and agents say they have narrowed their search to one "key suspect," but need more evidence.

"We're looking for a little bit more information,"Special Agent Dave Couvertier told ABCNews.com.

The FBI knows exactly what kind of information it needs, Couvertier said, but agents aren't giving specifics for fear of tipping the suspects off.

"We don't want those who are responsible for his disappearance to know what we know," Couvertier said. "We know that they are still in the area."

Shortly after Wiles vanished, Thomas and Pamela Wiles discovered a ransom note, the contents and location of which the FBI has not released. They began preparations to meet its demands, but communication was never established between them and the kidnappers.

Authorities believe those with information about Wiles' kidnapping had intimate knowledge of the family's business dealings and the family's company, National Flight Services.
