CHISHOLM, Minn. - It's hard for Chris Warner to return to the neighborhood.
His old home on 2nd Street in Chisholm sits boarded up. Abandoned.
It's where he and his wife raised their daughter LeeAnna.
On a late Saturday afternoon in June 2003, the little 5-year-old, nicknamed "Beaner", walked down the alley to knock on a friend's door. But no one was home.
"There was another gentleman who lived here," Chris Warner says, pointing at a house across the street. "And he actually saw her make it up this far. So. After that, that's where we lost her."
That was the last known moment LeeAnna was ever seen.
Back in 2003, Chris and Kaelin Warner made a desperate plea in front of television cameras.
"Beaner come home. We miss you. We're not going to stop looking for you. We're not going to sleep until we find you. We love you," they said.
That plea went unanswered as seemingly everyone in the town of 5,000 people looked for LeeAnna.
"We're relatively confident that she's not anywhere in that five square mile radius around Chisholm, just based on the thoroughness of our search," said St. Louis County Sheriff Ross Litman.
Authorities then figured that LeeAnna must have been kidnapped.
"It's like getting punched in the gut. I don't know, how do you explain it? Your life just stops," Warner said.
The crime seemed impossible in a city this size, just two blocks from Chisholm's idyllic downtown. But there were thousands of visitors that night for a concert and motorcycle run.
LeeAnna's footprints found near Chisholm's lake turned out to be from another day. Partially draining the lake found nothing. Authorities questioned several people, including 24-year-old Mathew Curtis who lived down the street whom they charged with child porn.
"All the agencies that worked on the case would've liked to have followed up with Matt. To try to determine what, if any, involvement he had. Unfortunately, that ended when he took his own life," Sheriff Litman said.
Litman calls that the best lead that ever came forward. Frustratingly few others surfaced.
Chisholm police are keeping the case open. They're looking into tips. But they still haven't received that major break.
"A real, good specific lead is what we would need today," said St. Louis County Undersheriff Dave Phillips.
"I think if it was somebody locally, they would have cracked by now," Warner said.
As the 15th anniversary of her disappearance nears,"Beaner" would be 20 if she's alive today. Her dad still believes she is.
"We haven't found anything to show that she's no longer with us. So I mean, that's probably the biggest clue we have," Warner said.
But even if she isn't alive, this family just wants to know.
"Someone's got to know something. Sooner or later, they'll get tired of hearing me, and they'll crack. Because I ain't backing off. I ain't quitting," Warner said.
Anyone with tips on the case is asked to call the Chisholm Police Department at (218) 254-7915.
