Alexa Foster died Wednesday after an interior wall inside a public bathroom in Crete's Tuxedo Park collapsed.
Foster was taking part in Saint James Catholic School's end of the year picnic when the accident occurred.
Witnesses say Foster and other students were using the bathroom to fill up water pistols when the wall came down.
According to one woman staying at the park, investigators worked until 4 a.m. Thursday morning removing and marking every concrete block in the interior wall in an effort to find out why the wall collapsed.
Funeral arraignments for Alexa have not been finalized. Contact Saint James Church for suggested memorials.
