The 25-year-old son of Greene County Judge Calvin Holden and Associate Judge Margaret Palmietto has been missing since New Year's Eve, and police in Sacramento, California, where the young man lives, have asked for the public's help.

"Yes, I am very concerned," Holden said Thursday night.

"I am currently on vacation in Australia and I'm leaving to head to Sacramento," he told the News-Leader.

Alexander Holden has lived in Sacramento for about two years and works for Amazon, his father said.

"He has no history of disappearing," he said.

Judge Holden's ex-wife, Palmietto, is Alexander's mother.

Calvin Holden said Palmietto was en route to Sacramento Thursday night.

Alexander Holden is not married but he has a girlfriend in Sacramento, his father said.

Calvin Holden said it was his son's girlfriend who notified him that Alexander was missing.

According to a news story in the Sacramento Bee, Alexander Holden was last seen New Year's Eve in downtown Sacramento wearing a tan pullover jacket. He is 6-foot-1 with brown eyes and about 190 pounds.
