Wetterling advocates ask that porch lights be left on

Monday marks 23 years since the day 11-year-old Jacob Wetterling was abducted by a masked gunman along a rural road. He was never seen again. The Jacob Wetterling Resource Center asks that people leave their porch lights on Monday night to honor the St. Joseph boy, an annual tradition, the Associated Press reports.

In August, a person of interest in the case, Dan Rassier, said investigators are violating his civil rights in their treatment of him, the Associated Press reported. He has been questioned multiple times, but his name didn't come out publicly until 2010, when authorities searched his family farm, the AP said.

Wetterling's mother, Patty, a one-time candidate for Congress, serves on the board of the National Child Protection Training Center.
