The 76-year-old “Danke Schoen” crooner and his wife, Kathleen Newton, told the Las Vegas Review-Journal the intruders fled when the couple arrived home following Newton’s show at Bally’s hotel-casino.
Newton family member and spokeswoman Tricia McCrone didn’t immediately respond to messages from The Associated Press.
The Newtons told the Review-Journal they’ve bolstered security at their 20-acre home and believe that home surveillance video will help police identify the suspects.
The Newtons moved to the house in 2013 following the bankruptcy sale of their nearby 40-acre estate, Casa de Shenandoah.
The gilded property is now a tourist attraction and museum. It featured gardens, pools, stables for Newton’s Arabian horses and a menagerie of exotic animals from flamingos to penguins. It and closed last month for renovations.
Newton’s best-known songs include his signature “Danke Schoen,” his 1965 version of “Red Roses for a Blue Lady,” and “Daddy Don’t You Walk So Fast,” which peaked at No. 4 on the Billboard charts in 1972.
