A Waldoboro man who was allegedly hiding loot from a $600,000-plus gold heist under a false floor in his basement has been extradited to Florida.

Kevin S. King, 53, “was picked up by Florida,” according to a dismissal form on file at the Lincoln County Courthouse. Assistant District Attorney Katie Hollstrom said King was picked up between Dec. 21, 2015 and Jan. 11.

King will return to face charges of grand theft and money laundering in excess of $100,000 in Florida.

Police seized an AR-15 assault rifle and at least five other firearms; “a large amount” of ammunition; 4 grams of heroin; prescription drugs; approximately $200,000 in Krugerrands, a gold coin of South Africa; and five 100-ounce silver bars with a value of approximately $10,000 during searches of King’s Bremen Road home Nov. 17 and 21, 2015.

At the time of his arrest in Waldoboro — the result of an investigation launched after a pair of incidents involving King exhibiting erratic behavior in the lobby of a Waldoboro doctor’s office — King was free on bail in a Florida case involving the Sept. 26, 2014 theft of 490 Krugerrands with a value of $633,000 from an 83-year-old collector in Jupiter, Fla.

According to The Palm Beach Post, King owned a coin shop in West Palm Beach, Fla. at the time of the theft. He met the 83-year-old man to broker the purchase of his collection — accumulated over 75 years — but, through trickery, allegedly stole it instead.

King was arrested in Florida July 28, 2015 and released the same day on a $30,000 bond.

King has an extensive criminal history dating to 1980, with numerous convictions for alcohol, drug, and weapons-related crimes. As a felon, he cannot legally possess firearms.

King still faces charges in Maine, of class C possession of a firearm by a prohibited person, class C receiving stolen property, and class C unlawful possession of scheduled drugs, according to court documents.

His bail conditions in Maine require his return at the conclusion of the Florida case.

“Florida is proceeding to trial in their case,” Hollstrom said.

King’s next court date in Maine is a dispositional conference at the Lincoln County Courthouse at 8:30 a.m. April 11. Hollstrom and King’s attorney will discuss the case with a judge, although King will not necessarily be present, according to Hollstrom.

Hollstrom is representing the state. Brunswick attorney Andrew Wright is representing King.
