Authorities say surveillance cameras have captured an image of the fugitive suspected of killing a Northern California city councilman and a land trust manager.

The Mendocino County Sheriff's Office on Monday told the Santa Rosa Press Democrat it believes the picture is of Aaron Bassler, for whom authorities have been scouring area forests since the shootings in August.

Deputies have been searching a 400-square-mile area for weeks, and have installed 40 cameras to aid their search.

In the photo, Bassler appears to be holding a high-caliber rifle and vandalizing a cabin.

Bassler is suspected of fatally shooting 69-year-old Fort Bragg City Councilman Jere Melo on Aug. 27 and 45-year-old Mendocino Land Trust land manager Matthew Coleman, who was found dead on Aug. 11.

Authorities believe they are closing in on Bassler.
