Authorities said that the heating system in Goldstein’s New Hampshire vacation home at 2962 Province Lake Road in Wakefield malfunctioned. The faulty system led to carbon monoxide leaking into the vacation home.

The Newton family of four was supposed to attend a holiday event in New Hampshire, New Hampshire State Fire Marshal Sean Toomey said in a press conference in December.

When they didn’t show up, family members requested local authorities check up on the Goldsteins at their vacation home, Toomey said.

There, authorities found the Goldsteins dead, according to the fire marshal. The home didn’t have any working carbon monoxide alarms inside.

The family died overnight, Toomey added. Three of them were found dead in a bedroom, while one was found in the bathroom.

Carbon monoxide deaths in New Hampshire have spiked in 2024, with 10 cases reported this year, according to Toomey. There are usually two to three cases per year.

If you have not spent some time playing around with AI, you absolutely should.

ChatGPT is one of the most commonly used pieces of AI. If you are unfamiliar, you can ask this artificial intelligence anything, and within seconds your questions are answered in an essay form.

And when I say you can ask or tell AI (ChatGPT) anything…I mean anything.

Recently, I asked ChatGPT to roast Portsmouth, New Hampshire, and it was absolutely hilarious. Check that out if you want to hear about the “yuppies moving from old Boston to new Boston.”

After AI torched Portsmouth, NH residents, I decided to see what ChatGPT had to say about New Hampshire’s most populated city: Manchester, New Hampshire.

What AI had to say about Manchester, New Hampshire:

Hands down the funniest thing ChatGPT said about Manchester was that the creator, or designer, “gave up halfway.”

The next roast, that everyone in New England will appreciate, is that Manchester’s main attraction is how quickly you can get from one chain restaurant to the next “without hitting a pothole.”

ChatGPT compared Manchester to a kid trying to act tough always trying to catch up to their older brother…Boston.

There was one backhanded compliment in the roast about Manchester. AI said that Manchester has “that gritty New England charm… if by “gritty” you mean “abandoned mills” and “forgotten dreams.””

Of course, as I will do with this continual AI series, I also ask ChatGPT to compliment Manchester, NH.

The good things AI has to say about Manchester, New Hampshire:

ChatGPT highlighted a sense of community in Manchester, NH that is not as tangible in other states.

The AI program also complimented the PEOPLE of Manchester, NH making it the community that it is.

In the words of ChatGPT, Manchester, “You’ve got something far more valuable (than a big city): authenticity. Keep being you, Manchester, because you’re doing it right.”
