A local security consultant says he is sure that whoever is behind the recent threats targeting high-ranking members of the Democratic party will be found.

Several suspicious devices were sent to high-profile Democrats, including former President Barack Obama, Chappaqua's Bill and Hillary Clinton and Bedford's George Soros.

A suspicious device was also sent to CNN offices in Manhattan.

"We are looking at the potential threat to life and limb to individuals whose only threat is running for public office," says security expert Bob Castelli.

Castelli, who served over two decades in law enforcement and served in the state Assembly, says the intended victims who had the bombs sent to their home addresses are targets, but targets that are pretty much untouchable.

"You don't think George Soros, who's a billionaire, walks down in his bathrobe and slippers to empty his mailbox, do you?," he says.

Castelli says even if those packages never even come close to their intended targets...he has no doubt whoever did this will be found.

He says the Secret Service knows who threatened those targets in the past.

Castelli says from the paper trail left behind, it seems that the attacks may have been carried out by a disgruntled individual. The FBI says it's still not sure.
