You might want to give it a day or a few..

my husband went to the hospital via ambulance a while back ago. I wanted to know exactly when the call was made so I tried to look online at the 911-emergency call log to get a better idea. That particular day in question was not listed. A few days later they were online again.

It was strange because even though that day wasn't listed, the days after it WERE listed online. I don't know why. Maybe they add to it or check their logs or something?

Check back later. If its still missing, then you'll know its a coverup. (Or if anything has been changed)
