Green died Monday after being left in a hot van outside Marlo's Magnificent Early Learning Center in Jonesboro after a field trip.
An affidavit obtained by The Atlanta Journal-Constitution says a checklist certifying that all children had been removed from the van was filled out before the van arrived at the center.
The affidavit was filed in connection with the arrests of center administrator Marlo Fallings, her daughter Quantabia Hopkins and a juvenile assistant.
It suggests that an hour or more elapsed between when center personnel realized that Jazmin was missing and when they phoned 911.
The women's attorney, Bruce Harvey, denied that Fallings and Hopkins falsified documents.
