Residents of Dayton held a special tree-lighting ceremony Monday night to honor Kathlynn Shepard.
A large evergreen tree on the northwest side of town was covered with 3,000 purple lights, Kathlynn's favorite color.
The lights were switched on during the ceremony.
Shepard's body was discovered last Friday night in the Des Moines River that an autopsy confirmed was her.
She was abducted while walking home from school on May 20.
Authorities believe Michael Klunder was the man who abducted Shepard.
He was found dead later on the day Shepard and her 12-year-old friend disappeared.
