The attorney for a nun accused of taking a 2-year-old girl and fleeing the country has entered a not guilty plea in a central Florida courtroom for a witness tampering charge.

Laura Caballero did not appear in court Monday. She's accused of attempting to "alter" the testimony of a woman who notarized a power-of-attorney that Caballero used to take the girl to Argentina.

She already pleaded not guilty to interfering with custody and false imprisonment.

Authorities say Caballero bullied a family in the U.S. illegally, taking their daughter to Argentina for six months.

Caballero was known as Sister Mary at the St. Filumena Catholic Church in Eustis. The church is not a Roman Catholic church affiliated with the Orlando Diocese or the Vatican, nor are its clergy and nuns.
