Vero Beach (KVRB): Cherokee on the grass after landing

[GeoffSM1]

I was searching out the following incident which appears in the FAA ASIAS data base.

'14-JAN-16
Time: 18:12:00Z
Regis#: N4297M
Aircraft Make: PIPER
Aircraft Model: PA28
Event Type: Incident
Location: VERO BEACH
State: Florida
Description: Aircraft landed long and ran off of the end of the runway.'

I was unable to find it in the archived file. Then a web search
produced the following info -
'A plane ended up in the grass during a landing after it ran off the runway Thursday morning. There were no injuries or damage to the plane.' (My underscoring to emphasise the time discrepancy.)

It wasn't difficult to find this incident in the archives

Note  that neither report refers to the emergency called before the landing.

I presume there was only the one excursion?
Can anyone throw any light on why an emergency was declared, please?
