Isaiah Marsh, the local man who has been missing since April 14, has been linked to a countywide pot-growing operation, Nevada County Sheriff Keith Royal said.
Drug Enforcement Administration agents and sheriff's deputies served search warrants on several homes in the county Monday, discovering a Nevada City man allegedly growing marijuana "clones" for sale and converting cargo trailers into hydroponic growing operations. One of the trailers allegedly had been sold to Marsh.
Robert Thompson, 52, allegedly had grown about 5,000 marijuana clones " essentially cuttings or plant starts " to sell to large-scale growers in the county. He also allegedly had purchased nine cargo trailers and had converted them into hydroponic growing operations. He has not been arrested pending the ongoing investigation.
Deputies confiscated one trailer at Thompson's residence in the 500 block of Jordan Street in Nevada City, and one in the 11000 block of Wild Turkey Lane in Smartsville. Both of those trailers were registered in Thompson's name.
Deputies also found and confiscated 30 pounds of processed marijuana and about 100 plants from the Jordan Street and Wild Turkey Lane locations, Royal said.
A third trailer allegedly was found at Marsh's residence in the 14000 block of Hobnob Way. No processed marijuana was found in that trailer, just residue, including leaves, Royal said.
"That indicated a prior marijuana-growing operation," he said.
Six trailers still have not been found, he added.
"At this point, we fear foul play," Royal said of Marsh. "He has disappeared off the face of the map and that is not like him."
Royal urged anyone with information about Marsh or the whereabouts of the missing trailers to call 265-1471.
