TALLAHASSEE, Fla.  — An ongoing criminal case against a former top aide to Florida Lt. Gov. Jennifer Carroll is transforming into a swirl of allegations about improper relationships, widespread illegal taping and other incidents inside Carroll’s office.

The allegations, which Carroll denies, were included in a court filing made late last week by the attorney representing Carletha Cole, who was arrested last October on charges that she gave an illegally taped conversation with another Carroll aide to a newspaper reporter.

Cole’s attorneys made the filing in response to prosecutors’ attempts to seal some evidence in the case.

In the filing, Cole contends that she witnessed Carroll and a top aide, Beatriz Ramos, in a “compromising position” inside Carroll’s office, that Carroll’s chief of staff secretly recorded conversations routinely at the direction of those working for Gov. Rick Scott, and that the trash can at Cole’s desk might have been deliberately set ablaze following an argument between her and Ramos.

Cole also said Ramos was living at Carroll’s home and at one point she was ordered by Ramos to find adjoining hotel rooms for Carroll and Ramos when they traveled. Cole said that she was “scolded” by an agent with Carroll’s security team when she placed Ramos next door to Carroll when the lieutenant governor and her husband traveled last summer to Puerto Rico. The agent told her to not do it again, Cole says, although he did not explain why.

Carroll, a former Navy officer who is also a mother of three, says the allegations are all lies.
