Authorities in central Minnesota say the remains of Jacob Wetterling, missing since 1989, have been found.
Patty Wetterling said in a text message to NBC affiliate KARE Saturday morning that 11-year-old Jacob Wetterling "has been found and our hearts are broken." She did not immediately respond to calls and text messages from The Associated Press.
The Stearns County Sheriff's Office said in a statement hours later that Jacob's remains were identified on Saturday.
Jacob was riding his bicycle with his brother and a friend on Oct. 22, 1989, when a masked gunman abducted him from a rural road near his home in St. Joseph, about 80 miles northwest of Minneapolis.

No one has been arrested or charged in his abduction, which led to changes in sex offender registration laws.

But last year, authorities took another look at the case, and were led to 53-year-old Danny Heinrich, a man they called a "person of interest" in Jacob's kidnapping.
Heinrich denied any involvement in Jacob's abduction, and was not charged with that crime. But he has pleaded not guilty to 25 federal child pornography charges and is scheduled to go on trial in those counts in October.
A law enforcement official told The Associated Press that Heinrich took authorities to a field in central Minnesota last week. The official, who spoke on condition of anonymity because of the ongoing case, said remains and other evidence were found.
The FBI has said that Heinrich matched the general description of a man who assaulted several boys in Paynesville from 1986 to 1988. Earlier this year, Heinrich's DNA was found on the sweatshirt of a 12-year-old boy who was kidnapped from Cold Spring and sexually assaulted nine months before Jacob's abduction.
Heinrich's attorney did not respond to an emailed request for comment Saturday.
Patty Wetterling always kept hope her son would be found alive. She became a national advocate for children, and with her husband, Jerry Wetterling, founded the Jacob Wetterling Resource Center, which works to help communities and families prevent child exploitation. In 1994, Congress passed a law named after Jacob Wetterling requiring states to establish sex offender registries.
Officials with the Jacob Wetterling Resource Center posted a statement on its website Saturday, saying they are in "deep grief."
"We didn't want Jacob's story to end this way," the statement said. "Our hearts are heavy, but we are being held up by all of the people who have been a part of making Jacob's Hope a light that will never be extinguished. ... Jacob, you are loved."
