Richard Wayne Landers Jr., was reportedly abducted when he was 5 years old. The 24-year-old Michael Landers now lives in the small central Minnesota town of Browerville, the Todd County Sheriff's Office said Friday.
Sheriff Peter Mikkelson said the investigation is ongoing and the case will be forwarded to federal authorities for possible charges.
It's unclear what Landers knew about his history, but authorities said he had lived with his grandparents since birth.
According to court records, Landers applied for the name change himself in November 2006, just a couple weeks after he turned 18. It wasn't immediately clear how long he had used the name Michael.
A home phone number for Landers could not be found, and he and his wife didn't respond to multiple messages sent through social networking sites.
But a posting from his Facebook account appeared Friday night on the Minneapolis television station KARE's Facebook page, saying: "For you people who jump to conclusions you should find out the whole story I was where I needed to be. My 'grandparents' were in the the right I dont care what anyone else thinks."
Landers didn't immediately respond to a follow-up message from The Associated Press seeking confirmation it was his statement. AP believes the Facebook account to be Landers' based on multiple links between it and confirmed friends and relatives.
His grandparents during a custody dispute with Landers' mother in July 1994 from Wolcottville, Ind., about 50 miles southeast of South Bend.
The mother and stepfather were unemployed and lived in a car, recalled John R. Russell, who spent several months investigating the disappearance with the LaGrange County Sheriff's Department in Indiana.
"These people (the grandparents) were nice people. It was wrong for them to do it, but I can understand why," Russell said. "But I also didn't think the child would be in any danger at all with them."
But an attorney for Landers' mother refuted claims that she was homeless. Attorney Richard Muntz said Landers' mother, Lisa Harter, spent only three days living in a car and it was with Landers' biological father, Richard W. Landers Sr.
She had divorced Landers' father by the time the grandparents obtained custody after Harter, who has mild developmental disabilities, moved into a group home that could not accommodate children, Muntz said.
Landers Sr. told the News-Sun in Kendalville, Ind., that Harter filed for divorce in 1990. He also said that he gave his parents temporary guardianship for one year because he didn't have a job.
After a while, Harter moved into an apartment and gained custody of her son on weekends, and she filed a petition to expand her custody rights when she remarried.
"The judge gave her custody on a trial basis, and before she could get him, that's when they left," Muntz told the AP late Friday.
He said the grandparents withdrew $5,000 out of a home equity line, went out for breakfast and left town.
"The trail on this case went cold the day they disappeared. There was no trace of them after they left the restaurant," he said.
The grandparents were charged with misdemeanor interference with custody, which was bumped up to a felony in 1999. But the charge was dismissed in 2008 after the case went cold.
Investigators reopened the case in September after a conversation between Richard Harter, Lisa Harter's husband, and an Indiana State Police detective who attended the same church prompted another search of Landers' Social Security number after several others over the years yielded no sign of him, Muntz said.
That turned up a man with the same number and birthday with an address in Long Prairie, about 100 miles northwest of Minneapolis.
Indiana State Police then contacted Minnesota law enforcement agencies, which began investigating along with the FBI and the Social Security Administration.
Minnesota officials say the grandparents - now living in Browerville under the assumed names Raymond Michael Iddings and Susan Kay Iddings - verified Landers' identity. They were known as Richard E. and Ruth A. Landers at the time of the abduction.
Now that Landers has been located, his mother is eager to talk to him, but that hasn't happened yet, Muntz said.
"What we're trying to do now is try to establish a way for Lisa and young Richard to get reacquainted," the attorney said.
Richard W. Landers Sr. also expressed interest in making contact with his son.
"I'm just thankful my boy is still alive, and I'll still get a chance to see him," he told the News-Sun. He also said he has forgiven his parents.
A woman who answered a phone number associated with the Iddingses declined a request for an interview. A couple who answered the door at their home declined to identify themselves and also refused an interview.
A spokeswoman with the U.S. Attorney's office in Minnesota, Jeanne Cooney, said charges in such a case could be related to non-custodial kidnapping, whether the child was exploited, abused, trafficked or being used to obtain benefits.
Michael Landers and his wife, who police say are expecting a child, share a plot of land with his grandparents a few miles outside of Browerville. There are two houses and two deteriorating barns on the property, and ten cars sat in the shared driveway.
Landers works at an auto parts store in Long Prairie, but wasn't at the store Friday and an employee declined an interview.
Raymond Iddings has worked since 1999 as a herdsman at Twin Eagle Dairy in nearby Clarissa, where owner Patrick Lunemann described him as a "dedicated, faithful" employee. Lunemann said he was in shock when he read a story about the case.
Lunemann said he knew Michael slightly, saying he stopped in occasion.
"(Landers) works at an auto parts place. That fits him perfectly, because Ray is kind of a motorhead and Michael is the same way," Lunemann said.
The town buzzed with the news, though. Rich Wall, a retired jeweler, said some residents speculated that some people knew of Landers' history but kept quiet. He said it was the most notable news since a grisly triple homicide there in 2003.
"My grandson called last night and said, 'Long Prairie made the news again,'" Wall said.
