About five weeks ago I taped an A=E special on The Partridge Family. They showed outtakes from the show. One outtake had Dave Madden (Ruben) breaking character and saying "Fred I'm going to kill you". It's true

That's not as bad as the time when Danny kept screwing up his lines when Danny and Reuben had a scene in a treehouse, and Madden threatened to throw him "out of the f***ing treehouse". I don't remember exactly where I read that, possibly in Cassidy's autobio.

That is strange because Danny Bonaduce himself claimed that Dave Madden was nice to him and was like a father to him since his real biological father was abusive and Dave Madden as well as Shirley Jones reportedly took Danny into their homes at times because they feared that Danny's father would really do harm to him.
Perhaps Dave Madden's threats were not really serious and just sarcastic. But who really knows?

Dannny Bonaduce seems to have narrowly escaped the fate of child actor Judith Barsi

Young And Helpless: She was a momager. She was always around her daughter. She was not an absentee parent at all. The thing is though, she had two issues. One was her husband who wanted more money so they needed to work their daughter more and the other issue was that to get more work for the daughter, she had to let her "rehearse" and "read for parts" with producers. The mom was more than willing, not only to appease her husband but also because she loved being on sets and basking in the glow of fame from her daughter. Her daughter had been acting from a very young age, but was not really molested or assaulted until she was about seven. She got a big break that year. She had been recommended by an A+ list director/producer who had seen her for a screen test. Uh huh. He had been consulted because of an interest in an upcoming television project. The A+ lister had been involved in a similar type project, but not for television. Anyway, the producer of the television show loved what he saw and told the mom he needed to spend some time alone with the girl to make sure she could handle the rigors of the episode. Two hours later he brought her back. One of the actresses in the episode who literally has played basically the same character for every episode of television she has been on for the past 30 years had tried to tell the mom what would happen if she let her daughter go with the producer. The mom told the actress to mind her own business. Fast forward a couple of years. Another producer. Another recommendation. Who did it come from? That A+ lister again. It was a project in his sphere even though he was not involved on a daily basis. This time it was a movie. For the very short amount of time the movie was being filmed, the nine year old girl was repeatedly sexually assaulted and raped. The mom let it happen. She pretended to not notice the men taking her daughter to their trailers or would tell others that the men wanted to go over lines or play video games. She had a never ending list of excuses. There was an actress on the set who had bit parts in the franchise. She never worked again after that movie because of what she saw. She said she could never work in an industry that would allow that to a little girl. It was shortly after filming wrapped that the girl began to cry out for help and was reluctant to ever be alone with anyone. She began to self harm even at that young age. Her family was no help. The mom wanted the fame and the dad needed the money. The dad had no idea though about the assaults. When he did find out, he blamed the mother and the daughter. He killed them both before killing himself.

You do realize that article is from a anonymous blog. The blog tries to minimize the father's role in the tragedy, and blames Hollywood and the mothers, which, of course is completely false. Here is a more accurate depiction of Judith Barsi's life:

If you were a child in the 1990s, the sound of Ducky’s baby voice from The Land Before Time excitedly saying “yep, yep, yep!” likely gives you a visceral reaction.

She. Was. So. Cute.

The optimistic dinosaur fundamentally misunderstood the concept of tense, using words like ‘finded’, ‘eated’ and ‘scarded’, but it didn’t matter because she was adorable, and had a happy little dinosaur family who loved her.

For the child actor who played Ducky, however, life was a very different story.

From the time she was born, Judith Eva Barsi was trained for Hollywood.

Her mother taught her about “posture and poise and voice,” and when she was five, she was discovered by chance by a camera crew at an ice skating rink. Over the next five years, she appeared in over 70 commercials, and a number of feature films, including Growing Pains, Cheers, Jaws The Revenge, All Dogs Go To Heaven, and The Land Before Time.

Speaking to the LA Times in August 1988, Judith’s agent, Ruth Hansen, said her client was a “bubbly, happy little girl,” whose success was in part due to the fact that she looked much younger than she was. She was small, and at 10 started receiving injections to spur her growth.

In the previous year, Hansen said, Judith had changed. She was distressed, and had started to pull out her eyelashes, and her cat’s whiskers.

At home, the young girl’s father was angry, and would repeatedly threaten his family, according to sources who spoke to the LA Times.

Judith’s mother had previously gone to police, accusing her partner of physical and verbal abuse, and threats on her life. Many people close to the family said Judith’s father spoke a number of times about killing his wife, while other times saying he would kill his young daughter, leaving his wife behind to suffer.

A neighbor recalled hearing Judith’s mother tell a story about Judith getting a brand new kite, but when she went to play with it, her father “broke it into as many pieces as he could”.

Judith reportedly told family friends she was afraid to go home, because she knew her father wanted to kill her mother.

In May, 1988, Hansen saw for the first time “how bad Judith was”.

The 10-year-old was scheduled for an audition, but started “crying hysterically” and “couldn’t talk”. Hansen, with some insight into Judith’s home life, decided to step in.

She encouraged her client’s mother to take her to a child psychologist, who, Hansen said, concluded that there were “extreme verbal, mental and emotional problems with this child”.

The psychologist reported Judith’s case to Children’s Services, who were told by Judith’s mother, Maria, that she had plans to divorce her husband and move out of the family home.

Maria had started to rent a separate apartment in May, but was yet to entirely move in. While Hansen encouraged the move, Maria told her in June that she wanted to stay in the home for Judith's birthday.

Then, on Monday, July 25, Judith missed an appointment. She was last seen riding her bike in the morning.

After that bike ride, Jozsef Barsi, 55, shot and killed his 48-year-old wife, his 10-year-old daughter, and then himself.

Judith would never get to see the final version of The Land Before Time, or All Dogs Go To Heaven, which were both released after her death. She had previously said that out of all her roles, voicing Ducky had been her favourite.

On her tombstone, Judith's family memorialized her affinity with Ducky, engraving her signature phrase "Yep! Yep! Yep!" below Judith's name.
