NEW YORK - Mayor Michael Bloomberg announced an online gun sting today that found buyers willing to sell weapons to customers who said they couldn?t pass background checks.

Among the guns purchased in the undercover operation was a model identical to the one police say was used to kill officer Peter Figoski Monday.

?It kind of explains how easy it is for these people in our community to have these type of guns in their possession,? says one local resident.

Bloomberg says investigators used Craigslist and other websites to contact 125 online gun sellers in 14 states. AP wire services were used in this report.
