It is very likely that this newspaper article is available on Find My Past (FMP). My DH has linked a number of newspaper articles he found on FMP to records of people on Ancestry.
I would suggest either getting a short term subscription for FMP or going to your local library (they often have access to Ancestry and/or FMP). Or, if you wait until we can PM again, then there are a number of people who will be able to help.
I (or, to be quite frank, it's usually my DH that digs into this - he can get a bit obsessive at times) have often found newspaper articles there that have helped clear up which ancestor we are looking for. These can be a great help.
Just one example (this was an attempted suicide and not an actual suicide) so I'm sure that it's not the same case.
I was trying to trace one particular person and I came across a census record that said he was an innkeeper at a particular pub in Gloucester in the 1871 census.
I then found several newspaper articles referencing him. Or so I thought.
It turned out that he had an uncle with the same name who was the actual licensee and he was just managing the pub.
I found this out when a newspaper article recounted the story of the uncle trying to commit suicide and being described as "an elderly man". The person I was tracing was 27 years old then so he definitely wasn't "elderly" at the time.
From that we were able to work out who was who.
The newspaper article (attached below) was from the "Gloucestershire Chronicle" of 2nd Sept 1871 page 8 column 1
TRYING TO HANG HIMSELF - On Friday, Samuel Lee, boatman, and landlord of the Colliers' Arms, an elderly man, was charged with trying to hang himself.
His grandson, a boy, then told that Lee and his wife returned home on the previous night, and had a quarrel, and that Lee thereupon said he wouldn't come home any more, and went and tied himself by an old silk handkerchief to a beam six foot high.
The boy cut him down, and fetched an uncle, to whom Lee promised that he would act so no more. The uncle fetched Sergt. Piff from Westgate street at half past ten, and the sergeant went to the place at once and found man and wife very drunk.
Lee was asked on Friday what was his explanation? He answered that he had backed a bill for 200 l.[£] for a brother-in-law, and that the matter caused a quarrel between himself and his wife; she was spoken of as being then in bed; and the case was adjourned that she might attend.
Mr Griffin now said that he had had conversation with Lee since Friday, and that the man seemed penitent; and he did, in fact, make promise that would not again seek to act so rashly.
His wife also attended, and denied that she was drunk as alleged on Friday. But Sergt. Piff said he was certain she was drunk, and the magistrates severely commented upon her conduct.
Lee was bound over in the sum of 20 l.[£], and to find two sureties of 10 l.[£] each.
I believe that the "uncle" referred to in the article was actually the nephew of the older man who had tried to hang himself. So he was actually the first cousin once removed of the young grandson that rescued his grandfather.
Although I can quite understand why the grandson might have referred to him as his uncle.

I think that Find My Past will likely be your best bet for this.
