The case against a Miami-Dade police officer accused of fondling young girls during traffic stops took a blow when one victim falsely accused her mother’s boyfriend of molesting her, according to newly released records.

The weakened cop case culminated earlier this month when former Miami-Dade Officer Juan Carlos Rodriguez pleaded guilty to a charge of child abuse with no great bodily harm and agreed to serve 5 years of probation.

Although a felony conviction will not show up on Rodriguez’s record, he cannot have record of the initial arrest wiped from his criminal history. He will also have to complete a treatment program for sex offenders and can no longer be a police officer in Florida.

In January, Miami-Dade police internal affairs detectives arrested Rodriguez after several teenage girls came forward to tell investigators that he had pulled them over in West Kendall and fondled them while frisking them.

In all, detectives located nine victims from five different incidents. Two of the victims were under the age of 15, young enough to warrant more serious sex crimes charges.

Rodriguez was charged with two counts of lewd and lascivious battery on a minor, with the other victims expected to be used as witnesses in the case.

One of the underage victims, known by her initials A.C., later accused her mother’s live-in boyfriend of molestation and he was arrested.

But the girl eventually admitted she concocted the allegations against him. The reason: the boyfriend had become more strict after it was discovered she had been out drinking and smoking the night Rodriguez pulled her and her friends over. Prosecutors quickly dropped the charge against her mother’s boyfriend.

According to a Miami-Dade State Attorney’s memo, prosecutors had no choice but to remove the teen from the Rodriguez case because “because her credibility would so easily be attacked.”

“Once A.C. had to be eliminated from consideration as a victim in the case against Rodriguez, the case was far less provable as an L&L Molestation case,” the memo said.

The rest of the victims did not object to the plea deal for the disgraced cop. “The victims were relieved that they did not have testify in open court about their encounters with the defendant,” according to the memo.
