Ricci Martin, an entertainer and the youngest son of Dean Martin, has died, according to family members. He was 62.

“My heart breaks to announce the untimely death of my beloved brother,” Ricci’s sister Deana wrote on Facebook. “My family and I are devastated. He was one of the sweetest souls I have ever known. Ricci’s kindness, sweetness and loving nature will be missed more than words can say. ‘Rest in peace, Ricci. I love you!'”

The cause of death is unknown, though earlier this year he canceled his U.K. tour dates after falling on the ice in front of his house. As he explained in a Facebook post in April, he was subsequently hospitalized and diagnosed “with a subdural hematoma as a result of the fall.” He stated he had to stop treatment for a deep vein thrombosis, which was at risk of causing a potentially fatal pulmonary embolism. Ricci was recuperating at the time.
