"Columbo" star Bruce Kirby has passed away at the age of 95, his son confirmed.

Bruce's son, John Kirby, confirmed in a lengthy Facebook post that his father died on Sunday in Los Angeles.

John failed to mention his father's cause of death, but he noted that Bruce died peacefully on the night of January 25.

"My heart is heavy but grateful for all the extra blessed years together. My Step-Mom ROZ's Love & devotion was remarkable & a major force in keeping him alive so long," the acting coach penned.

In his tribute to the late actor, he also mentioned that he was a great father to him and his older brother, Bruno Kirby.

Meanwhile, John took his time to thank all the people who were there before Bruce Kirby's death.

He expressed his gratitude toward a man named Pedro, who reportedly became a 24-hour caregiver to his father. A woman named Susan Sullivan also reportedly looked out for his father and stepmother, Roz.

John ended his heartfelt tribute with a "Thank You" message to Bruce, saying: "Thank You DAD for everything you taught me about Acting & how to have such a strong work ethic while sharing your love for the Arts & the Craft of it all. I will miss You & Love You always."

In some parts of his Facebook post, he recalled the late actor's milestones--from his big-screen projects to his TV shows.
