At 7:25 on the morning of December 14th, the Associated Press tweeted that police had responded to a report of a school shooting.
Followed with several retweets shortly after this.
The Ruler, @3CarryOnItems retweeted at 7:26 AM.
Then Ron, @iAmBoiGenius retweeted at 7:27 AM.
And Triple L, @LarryLankLank retweeted at 7:33 AM.
Finally, The Ruler, @3CarryOnItems retweeted again at 7:36 AM.
So what's unusual about the timing of all these tweets?
At about 9:35 a.m., using his mother's Bushmaster XM-15, Lanza shot his way through a locked glass door at the front of the school. He was wearing black clothing, earplugs and an olive green utility vest carrying magazines for the Bushmaster. Initial reports that he had been wearing body armor were incorrect. Some of those present heard initial shots on the school intercom system, which was being used for morning announcements.

Now when you tweet, it's timed-stamped with the time-zone you set in your account. According to sources, the shooting didn't begin until around 9:35 AM EST, but the AP tweeted about the event two hours before it happened.
I suppose the AP could be tweeting from Denver, CO; even though they're headquartered in New York, (screenshot), but even if they were, that still doesn't account for the minutes. How could the AP tweet "breaking" news at 25 minutes past the hour, when no one should have needed to call the police until 35 minutes past the hour?
