PORTLAND, Ore. (CBS/KOIN/AP) Searchers returned to a Portland-area island for the second consecutive weekend looking for clues to the whereabouts of missing 8-year-old, Kyron Horman.
This past weekend more than 100 people scoured Sauvie Island, about 15 miles outside of Portland, seeking evidence that may help find the second grader who disappeared five months ago.
The last person to report seeing Kyron is his stepmother, Terri Horman, who said she last saw him walking toward his classroom after a school science fair.
Despite rain, dozens of volunteers showed up again this weekend and dedicated their time to aid in the search.
Sheriff's Office spokesperson Mary Lindstrand said the searching is not based on any new information, but, rather they are following up on leads from the very beginning of the investigation, reports CBS affiliate KOIN.
Teams used string to grid off areas they already searched and while there were no specific focal points for the search, many people concentrated on a road that runs north-south on the large island.
"The grid lines give them a line to follow so they know that the area inside the line has been searched," Lindstrand told KOIN." "It just gives them a straight place to start from."
Most of the searchers worked on foot, but horses, canine units and ATVs were also used. Law officers would not indicate whether any significant clues were found as the weekend's search came to a halt Sunday evening.
Authorities have offered a $50,000 reward for information leading to the missing boy.
Anyone with information about the case is asked to contact the Tip Line at 503-261-2847.
