A "person of interest" in the suspected double homicide of a Maine couple was arraigned Wednesday afternoon in Lake County Superior Court on marijuana cultivation charges.

Robby Alan Beasley, 29, was charged with cultivation of marijuana, possession for sale of marijuana and maintaining a place for drug sales, according to the Lake County District Attorney's Office.

Beasley, who did not enter a plea, is being held on $1 million bail.

Lake County Sheriff's authorities found 96 marijuana plants at one of Beasley's two Lake County residences while serving a fugitive warrant issued in Maine, where he, like the victims, formerly resided. The warrant was issued for a probation violation related to criminal threats and assault charges, law officials said.

Booking records list Beasley's occupation as painter.

The deceased couple, Frank and Yvette Maddox, 32 and 40, came to Clearlake several months ago to work in Beasley's marijuana cultivation operation, said Lake County Sheriff's Capt. James Bauman.

They disappeared in late January after agreeing to give Beasley a ride to the Sacramento airport, he said.

Their bodies were found last week along Morgan Valley Road about six miles east of Lower Lake. Two Sonoma County men spotted the corpses when they stopped to take a break from driving.

Autopsies was being performed Wednesday at the Napa County Coroner's Office, Bauman said. He does not expect the results to be released until Thursday.

Authorities are searching for the dead couple's vehicle, a 1982 Toyota pickup, he said. It was either tan, beige or pale yellow with a black camper shell, Bauman said.
