This happens to be a coincidence of the same name, where the deceased man lived in Connecticut and had a full biography that is different than the full verifiable biography of the Ohio shooter. Snopes, which is sometimes misleading, happens to have done an accurate investigation of this claim, showing they are not the same individual.

: BOOOOOOM ANOTHER BLOCKBUSTER: ORIGINAL NEWSPAPER THAT HAD
: 2014 OBITUARY FOR OHIO SHOOTER RECOVERED, IT IS HERE

:

: The Ohio shooter's obituary appeared on page B7 in the Feb 23

: 2014 issue of the Hartford Courant.

: Now fully confirmed to be a match. The Ohio shooter, who
: died in 2014, SHOT HIS OWN SISTER LAST SATURDAY, and she's
: in his 2014 obituary!!!! HA HA, this is not a hoax, it is
: directly from the source which is clearly embedded in the
: capture linked in the headline. This was recovered by
: Astromutt at Godlikeproductions, who subscribed to the
: paper to get the back issues and LOW AND BEHOLD, THERE IT
: WAS. This proves the Ohio shooting could not possibly have
: happened.

: Here is what happened: The mom owns a security company that
: contracts with the government. She decided to use all the
: pics of her dead son to front as a shooter. And she even
: said her own daughter died!!! It just does not get any
: better than this, that is really what happened, the Dayton
: shooting NEVER HAPPENED and the obituary proves it.
