A Broward Sheriff Office detective was arrested after using his cell phone to allegedly tape a conversation with a witness in a case against two Fort Lauderdale police officers charged with kidnapping and misconduct.
On Wednesday Det. Anthony Costanzo turned himself in on felony charges of tampering with a witness, tampering with evidence, disclosure of confidential information, and use of a two-way communication device, according to a release from State Attorney Michael J. Satz.
In January, Costanzo aided in the arrest of a Bonita Liston for possession of a controlled substance, charges later dropped when she provided her valid prescription.
During the incident, Costanzo learned that Liston was also a witness in a previous case against Fort Lauderdale officers Billy Koepke and Brian Dodge. The two officers are under investigation for racketeering, extortion, false imprisonment, grand theft, falsifying criminal records, kidnapping and misconduct.
Costanzo allegedly took out his cell phone to tape their discussion about the case.
Costanzo probed Liston about her and her husband’s interaction with the officers last year, “with the intent of misleading her about the circumstances surrounding the criminal proceeding against Billy Koepke,” according to the arrest affidavit.
Afterward, Costanzo reportedly sent the recording to his "buddy" Koepke as well as to the Police Benevolent Association’s lawyer. He told his BSO Sergeant Patrick Murray about what he did, and the sergeant reported the incident, according to the affidavit.
In the recording, according to SAO, Costanzo can be heard suggesting to Liston that her husband had been arrested and was cooperating with police "so technically he wasn't being kidnapped."
When FBI forensic analysts later examined Costanzo’s phone, they determined that the video was removed from the phone.
According to NBC Miami, Costanzo was released Wednesday evening after posting $5,000 bond.WATCH: Miami cop arrested for driving 120 miles per hour:
