Richard Belzer's family is ready to pay public tribute to the late actor.
The Law & Order: Special Victims Unit star's loved ones exclusively shared a statement with PEOPLE, saying they "are overwhelmed with the beautiful and heartfelt memories, admirations and love from Richard's family, friends, acquaintances and admirers."
"It has been truly helpful for us, his family, in traversing through this challenging time. So thank you," Belzer's family continues. "We have had a delay in making a statement in regards to his passing because, although he did have several health issues that had been difficult but not terminal, he experienced quite a sudden decline in health that caught us completely off guard, which lead to his passing."
Belzer "passed away very peacefully in his sleep early Sunday morning on February 19th at his home in Beaulieu-sur-Mer, France, with his wife of 40 years and eldest daughter by his side," his family shares.
"His youngest daughter was unable to be there with us, but will be joining us soon. Due to the sudden nature of his passing, we apologize that we were unable to reach [out] until now, as we needed the time to process through this, gather ourselves and our thoughts," the statement continues.
Belzer's family adds, "We so appreciate the outpouring of support from all of our family and friends. And thank you so much for those of you that have been so respectful of our need for privacy and solace during this difficult time."
The cause of his death is still unknown. However, a small family service will be held Friday afternoon in Colomars, France.
PEOPLE confirmed Belzer's death on Sunday via former Late Show with David Letterman writer Bill Scheft.
"His last words were, 'F--- you, motherf---er,'" Scheft told PEOPLE, noting that Belzer died "peacefully with family at his side."
