According to records I have,I have a John Singleton, died 16th August 1901,buried 21 August 1901 in Widnes Cemetery. aged 25 years, this age agrees with yours. If you send me your email address by pm I will send you a copy of the sheet,it has also some other Singletons on it who all resided in the same street, in fact next door but one .
Regarding newspaper coverage, Widnes Library hold on film copies of the Widnes Weekly News, you might find a reference to your relatives accident,keep in mind that at that time there were a great deal of accidents in the Widnes area so the report might only be a few lines.
