#Yale RT @yalealumnimag Most @Yale students are away on Thanksgiving break. Undergrads and most grad schools do not have classes this week.

From New Haven PD: Man called, claimed roommate was going to Yale with long gun. No shots fired, no weapon found, no one in custody.

— Matthew Campbell (@mgmcampbell) November 25, 2013

PD have interviewed witnesses who claim they saw suspect.

Yale press conference starting now. #wfsb for live update

— Matthew Campbell (@mgmcampbell) November 25, 2013

Caller did not ID himself, caller phoned from pay phone. Caller has not been identified yet. #Yale

— Matthew Campbell (@mgmcampbell) November 25, 2013

No reported gunfire, no reported injuries.

— Matthew Campbell (@mgmcampbell) November 25, 2013

#Yale is still in lockdown. SWAT has been going building to building. Focused on Old Campus right now.

— Matthew Campbell (@mgmcampbell) November 25, 2013

FBI, ATF, Yale PD, CT State PD all involved in #Yale lockdown

— Matthew Campbell (@mgmcampbell) November 25, 2013

At least two witnesses are being interviewed. Those reported sightings of man with long gun.

— Matthew Campbell (@mgmcampbell) November 25, 2013

No description of suspect, unsure if it's even a student. Old Campus being considered the hot zone.

— Matthew Campbell (@mgmcampbell) November 25, 2013

Search is only contained to Yale at this point.

— Matthew Campbell (@mgmcampbell) November 25, 2013

Call lasted just a few seconds, caller was calm, reported this in a "matter of fact" way.

— Matthew Campbell (@mgmcampbell) November 25, 2013

No description of suspect is available because the several descriptions that have come in, were not consistent. #Yale

— Matthew Campbell (@mgmcampbell) November 25, 2013

Police are asking drivers to stay away from Yale and the New Haven green. Traffic is a nightmare.

— Matthew Campbell (@mgmcampbell) November 25, 2013

NHPD: Investigation ongoing, there are still a number of students on campus, even though they are on Thanksgiving break.

— Matthew Campbell (@mgmcampbell) November 25, 2013

PD are having problems during the door to door dorm checks. Doors don't have peepholes, students are not believing it's PD when they knock.

— Matthew Campbell (@mgmcampbell) November 25, 2013

PD says the witnesses who reported "man w/long gun" may have actually spotted a responding officer, instead of actual gun man.

— Matthew Campbell (@mgmcampbell) November 25, 2013

All clear will only be given when PD are confident everyone is safe, but say they will still be out here for hours.

— Matthew Campbell (@mgmcampbell) November 25, 2013

Yale Spokesperson: Old Campus is made up of primarily undergraduate dorms. This is still the hot zone of the investigation.

— Matthew Campbell (@mgmcampbell) November 25, 2013

NHPD just clarified that initial anonymous 911 came from Columbus Ave pay phone at 9:48, not 9:30 as earlier reported.

— Matthew Campbell (@mgmcampbell) November 25, 2013

Caller in the #Yale incident used phone booth on the 300 block of Columbus Ave. between Howard/Hallock.

— Matthew Campbell (@mgmcampbell) November 25, 2013

We went to that area around 11:15 this morning and didn't notice any police activity or anything else unusual.

— Matthew Campbell (@mgmcampbell) November 25, 2013

FBI is now listening to that tape, using voice recognition. The anonymous caller is who set this in motion and PD would love to find him.
