Three people were charged with trying pass counterfeit $100 bills at a local convenience store Friday night.

The incident took place about 8:45 p.m. Friday when Officer Thomas Casimiro spotted a vehicle in the parking lot at Cumberland Farms on Post Road East matching the description issued in a bulletin issued 15 minutes earlier by Fairfield police.

More patrol units were called to the scene as one of the men made a transaction in the convenience store. The man and his companions were stopped for questioning by the officers, who said they subsequently found the three suspects in possession of five counterfeit $100 bills, $1,100 in fraudulent travelers' checks, $800 in cash and several receipts.

The case continues to be investigated by Westport police with assistance from the Secret Service.

The three people taken into custody were:

Rennie Fernandez, 28, of New Haven, charged with 16 counts of first-degree forgery and tampering with evidence.

Aton Austin, 30, of Brooklyn, N.Y., charged with five counts of first-degree forgery.

Melissa Menifield, 19, of Brooklyn, N.Y., charged with five counts of first-degree forgery and one count of second-degree forgery.

And even though Norwalk Superior Court Judge Bruce Huddock on Monday cut their initial $100,000 bonds in half, they could not raise the money and will remain in jail.

They are now scheduled to return to court June 18.
