(AP) — A timeline of events related to the abduction of 11-year-old Jacob Wetterling of St. Joseph, Minnesota:
Oct. 22, 1989: Jacob Wetterling, 11, is abducted from a rural road as he rode bikes with his brother and a friend by a masked gunman near his home about 80 miles northwest of Minneapolis.
Oct. 26, 1989: Deputies on horseback and hundreds of people search for Jacob, but find nothing.
Oct. 29, 1989: About 225 National Guard troops and 80 Minnesota Department of Natural Resources workers unsuccessfully search for clues. Supporters of the boy’s family release more than 1,000 white balloons after a church service.
December 1989: Investigators are deluged with tips after they release a new sketch of a suspect. Authorities also say they believe the man who kidnapped Jacob was responsible for the January 1989 abduction and sexual assault of a boy in nearby Cold Spring.
