In a tragic coincidence, Rob Reiner‘s All in the Family costar Carroll O’Connor also dealt publicly with his troubled son’s addiction battles.

Daily Mail is examining the troubled father-son relationships in the wake of Rob’s son Nick Reiner, 32, being charged first-degree murder in the December 14 murders of his parents Rob, 78, and Michele, 70, in their Brentwood, California home.

Carroll O’Connor, who died at 76 in June of 2001 from a fatal heart attack, had fought hard to help his son Hugh amid his own drug battle until his tragic suicide at 32 in March of 1995.

On All in the Family – regarded as one of the most consequential TV shows in the history of the medium – O’Connor played the role of curmudgeon Archie Bunker for 207 episodes throughout the show’s nine-season run.

Reiner portrayed his liberal son-in-law Michael ‘Meathead’ Stivic on 185 episodes of the legendary series from creator Norman Lear.  

The two characters often had memorable dialogue amid their differing sensibilities during a time of social change in the U.S. – with Stivic tangling with his father-in-law over social, racial and political topics.

Carroll O’Connor and his spouse Nancy adopted Hugh while they were making the 1963 motion picture Cleopatra in Rome, Italy. He would be the couple’s only child.

Following All in the Family, O’Connor reprised his signature role on the spinoff Archie Bunker’s Place from 1979–1983 before finding success on the small screen with the police drama In the Heat of the Night.

O’Connor’s son Hugh played Officer Lonnie Jamison alongside him on the procedural drama.

Hugh’s acting came amid an ongoing battle with depression and drug addiction that resulted in his tragic suicide via gunshot on March 28, 1995.

Prior to taking his own life, Hugh contacted his father in a phone call informing him of his plans, according to People. 

Carroll contacted the local authorities in Pacific Palisades, California, but Hugh was deceased by the time they arrived.

Carroll later said Hugh son was ‘sitting on the sofa’ and tragically ended his life with ‘one shot to the head,’ according to the outlet.

Hugh had been dealing with marital problems on the third anniversary of his wedding to wardrobe assistant Angela Clayton, who he shared a two-year-old son with that Carroll and his wife had been caring for.

Authority subsequently said that Hugh had large amounts of cocaine in his bloodstream when he had died.

Carroll O’Connor later said that addiction was the ultimate reason for his son taking his own life.

‘He had that monkey on his back, and he couldn’t get rid of it,’ the TV legend said, according to People. 

Carroll O’Connor and wife Nancy subsequently told People that Hugh’s battle with substance abuse began after a Hodgkin’s disease diagnosis when he was 16.

After he had a malignant lump removed from his neck, Hugh began smoking marijuana to deal with side effects from radiation. 

That led into alcoholism and abuse of quaaludes prior to escalating his drug use to substances such as amphetamines, cocaine and prescription medication.

Carroll O’Connor said that his son Hugh had stints in rehab facilities on three separate occasions.

In the wake of his son’s tragic suicide, Carroll O’Connor got more involved with politics to prevent kids from using drugs.

In 1997, the state of California passed a law O’Connor campaign for enabling families to sue drug dealers for financial costs stemming from complications linked to medical treatment and rehab rehabilitation. States including Florida, Hawaii, Illinois and Michigan adopted similar laws.

The man who was convicted of selling Hugh cocaine, Harry Thomas Perzigian, was sentenced to a year in jail in connection with possession of the illegal narcotic, as well as selling it to Hugh.

‘Hugh was an addict, probably without hope,’ O’Connor said, according to People. ‘Harry kept feeding him this stuff. We feel this guy indirectly was the cause of our loss.’

Carroll O’Connor spoke with People magazine about the deep sense of grief he felt, a year after his son’s death in a 1996 interview.

‘I think of Hugh every day, but I don’t think of him sadly every day,’ Carroll said. ‘Most of my thoughts of him are very joyful.

‘But then there are the times – thank God, not too many – when something makes me very sad.

He added, ‘Nancy will look at me and say, “You look bad. Well, I was having a bad time an hour ago too.” And we put our arms around each other and say, “It’ll be alright soon.”‘

Nick Reiner had past been candid about his issues with substance abuse, which led to homelessness and repeated rehab stints. He and his father explored their complicated relationship in the 2016 film Being Charlie.

Rob Reiner told the AP in a 2016 interview that making the motion picture with Nick ‘forced us to understand ourselves better than we had.’

The filmmaker added, ‘I told Nick while we were making it, I said, “You know it doesn’t matter, whatever happens to this thing, we won already. This has already been good.” We’ve worked through a lot of stuff.’

Nick told People in 2016 interview that he had been to rehab on 17 occasions at that time, when he was 22-years-old.

Nick said that he had been confronted by family with the ultimatum of entering rehab or hitting the streets on multiple occasions – at times, choosing the latter.

‘If I wanted to do it my way and not go to the programs they were suggesting, then I had to be homeless,’ Nick said. ‘I spent nights on the street. I spent weeks on the street. It was not fun.’

Nick said that he had experienced homelessness in states including Texas, New Jersey and Maine.

‘If I wanted to do it my way and not go to the programs they were suggesting, then I had to be homeless,’ he said. ‘I’ve been home for a really long time, and I’ve sort of gotten acclimated back to being in LA and being around my family.’
