Hugh Edward Ralph O'Connor (April 7, 1962 – March 28, 1995) was an American actor, known for his role as Det./ Lt. Lonnie Jamison on the television drama In the Heat of the Night from 1988-1995.
He was married to Angela Clayton, a wardrobe assistant on In the Heat of the Night, on March 28, 1992, and their son Sean Carroll O'Connor was born in 1993.
On March 28, 1995, the third anniversary of his marriage, O'Connor called his father to tell him he was going to end his life. He told his father he believed he could not beat the drugs and could not face another drug rehabilitation program. Carroll called the police, who arrived at Hugh's Pacific Palisades, California home just as he shot himself in the head. The police later determined he had cocaine in his blood.
Hugh O'Connor was cremated and his remains were originally buried at the Church of St. Susanna in Rome, Italy. Later, his remains were moved to the North American College in Rome. Today, he has a cenotaph at the Church of St. Susanna and at his father's gravesite in Los Angeles, leading many people to believe that he is buried at either place.
