ROSEBURG, Ore. -- Two Facebook groups held a vigil for missing Portland boy Kyron Horman in Roseburg Sunday night.

The vigil was held near the home of Kyron's stepmother, Terri Horman.

She was the last known person to have seen Kyron the morning he disappeared. June 4, 2010.

She has not been named a person of interest.

But one of the organizers says the group hopes this vigil will push her to talk about the boy's disappearance.

New billboards were also drawing attention to the search. They were set up along Interstate 205, Highway 16 and Interstate 5.

More of them were expected to go up in Roseburg and Medford.
