Authorities in California are seeking help to locate a New York man with ties to European royalty who went missing in the L.A. area.
Attilio Brillembourg, 53, was last seen at 1 a.m. on May 18 in Malibu.
He is the stepbrother of Princess Tatiana of Greece, according to the Daily Beast. His father, also named Attilio Brillembourg, had a prominent role in her wedding.
The Los Angeles County Sheriff's Department issued a special bulletin about the disappearance.
"There is concern for Mr. Brillembourg's well-being," the bulletin stated.
He was last seen wearing a blue shirt, gray pants and no shoes.
Brillembourg is 5 feet 10 inches tall and weighs 165 pounds. He has gray hair, green eyes and a tattoo on his upper thigh.
Tatiana Blatnik was awarded the title when she married Prince Nikolaos of Greece in 2010. They announced last month that they were divorcing.
Nikolaos is the second son of King Constantine of Greece and Queen Anne-Marie of Greece. Constantine II was the King of Greece until the monarchy was abolished in 1973.
Tatiana Blatnik was an events planner for Diane Von Furstenburg in London before the marriage.
