» A caveat: Be careful not to overly lean on this speculation, however. After CBS published their story, they added this note: "In response to this piece, Lt. J. Paul Vance of the Connecticut State Police told CBS News that the investigation into the motive for the Newtown shooting has not been completed and therefore any statements about the shooter’s intent are mere speculation."
Adam Lanza, who sources tell @cbsnews was the shooter, was 20 years old.His brother, Ryan, is 24 and is being questioned in New Jersey

So it looks like Adam Lanza is the suspect, not his brother, Ryan, as was earlier reported.
