Very sorry to hear about your daughter Julia... that alone should say it all!!!
If everyone is now paying attention... you may have noticed Cell Phones have GPS locaters in every phone, specifically for locating 911 calls. You can disable GPS for everything but 911.
I think the FCC should require the same GPS in VOIP equipment making it possible to track and locate the origin of a 911 call.
I called 911 a few days ago in the Bay Area, Ca. and got the police records department voicemail tree, telling me that if it was an emergency call for me to hang up and call 911.
