Here are the 911 calls with time stamps:
CALL 1, 9:35:39, 24 seconds
CALL 2 released on the recording is a duplicate of Call 1.
CALL 3, 9:36:13 a.m., Rick Thorne, acting head custodian, 3 minutes & 52 seconds
CALL 4, 9:37:06, 42 seconds
CALL 5, 9:40:02 a.m., 5 minutes & 22 seconds
CALL 6, at 9:40:20, Rick Thorne, 3 minutes & 24 seconds
CALL 7, 9:43:55 a.m., Rick Thorne, 4 minutes & 10 seconds
Part way through CALL 7 Rick Thorne hears and then sees the officers coming in — which indicate that the Newtown Police entered the building at about 9:45 apparently from the back of the school. A little later entry was made from the front
The Newtown police and their report say they went in first but the state police and their Sandy Hook report say they all went in together when the state police got there at 9:46. Police chiefs report says it was later than 9:46 when they got there.
There is tension between these two agencies trying to take credit but then there is this from the 911 tapes:
Here is the police dispatch to compare to the 911 calls:

1] Interview with one of two mothers who witnessed the 8 to 10 kids running down to the firehouse, the Lanza’s Honda with black sweatshirts strewn on the ground, the broken plate glass window at the front door, no police around,
the unusual quiet, then gunshots ring out from inside the school.

2] Marilyn Gudsnuk — sees kids running from the school in front of the firehouse, 7 or 8 police cars were going in opposite direction, and then gunshots ring out — probably the same ones that the two other women heard.

Toward the end of Call #3 7 gunshots can be heard. These aren’t the ones the women heard but the shots probably fired in Soto’s room after which the kids made their break for the firehouse.
CALL 3 began at 9:36:13 a.m. with Rick Thorne, acting head custodian, and lasted 3 minutes & 52 seconds meaning that those shots were taking place right at 9:40. Those are the shots after which the 10 kids made their escape.
How long does it take 10 first graders to run a quarter mile???
The next set of gunshots are the ones reported at around 9:46 as LE are entering the school. The 911 calls particularly those of Rick Thorne released thus far all ended before 9:46 — thus those shots are not recorded..
