Connecticut School Shooting: Media/Reporters ID the a wrong Guy

Numerous TV news outlets and websites are scrambling after they named a man and showed his picture, claiming he was the shooter in the Connecticut school massacre, but it seems they had the wrong guy.

Hordes of reporters have descended on the home of Ryan Lanza in New Jersey, hoping to speak to members of his family after the horrific school shooting in Connecticut this morning(depending on your Time Zone) -- but there's one problem ... it's the wrong Ryan.

The outlets claimed Ryan Lanza killed at least 26 people at Sandy Hook Elementary School, including at least 20 children.  Some of the outlets also splashed his pic on the screen.

Meanwhile Someone began posting messages on Ryan's Facebook page denying he's the shooter, even saying "F**k you CNN.  It wasn't me."  FYI ... CNN didn't post the pic -- it was iReportCNN, a user-generated forum.

Ryan's mother Nannette tells TMZ, her son -- 26-year-old Ryan John Lanza -- is a corrections officer-in-training at the Camden County Correctional Academy.

The Ryan Lanza that was initially identified as the possible school shooter -- who gunned down 26 people at the school, including 20 small children -- is 24 years old. (Police have since identified Ryan's brother Adam as the real shooter.)

Nannette says her phone's been ringing off the hook for several hours -- accumulating as many as 21 voicemail messages per hour -- and reporters are still sitting outside her house.

Nannette tells TMZ, she hasn't been able to get in touch with her son since news broke of the shooting -- but she insists that's because cell phones are prohibited at the correctional academy. NBC reported they may have gotten the name wrong because the shooter had an ID in his pocket that made them believe Ryan Lanza was the culprit. 

Law enforcement sources now tell AP the shooter is Ryan's brother, Adam.
