This is why getting the suspect’s name right is important. (FWIW, Ryan Lanza is in custody — for questioning — while Adam Lanza is the alleged suspect according to the Associated Press, though the Connecticut state police won’t confirm. He was found dead. The two had their names inverted in earlier reports.
It is not clear if Ryan Lanza had a role or not.)
UPDATE: The AP reports that Ryan Lanza appears not to have a tie to the shooting. Which makes this point even more relevant.
