Murder suspects Craig Arno, 44, and Jessica Kisby, 24, pleaded not guilty to kidnapping and carjacking charges Wednesday during a brief hearing in Atlantic County Superior Court.
The couple, who remain targets of a murder investigation in the death of North Jersey grocer Martin Caballero, said little as they appeared in orange jumpsuits and handcuffs before Judge Michael Donio.
Donio set bail at $500,000 for Arno, $400,000 for Kisby.
"In the near future, we anticipate new charges," Atlantic County Prosecutor Theodore Housel told Donio.
Those charges are expected to be for murder.
A body, believed to be Caballero's, was discovered on a farm road in Atlantic County on Sunday, 10 days after the alleged carjacking.
Caballero, of Hudson County, disappeared on May 21, after dropping his wife and daughter at the Trump Taj Mahal Casino Resort in Atlantic City, where they planned to celebrate their daughter's 22d birthday.
Authorities allege that Arno and Kisby confronted Caballero in a parking garage and kidnapped him.
Caballero's car was later found on fire in Gloucester Township, Camden County, about 50 miles from Atlantic City.
Arno and Kisby were arrested late last week at a motel outside Atlantic City.
