Ex-cop busted again — this time, claiming to work in cyber crime and anti-terrorism

Martha Alemán just can’t quit Miami-Dade police.

Alemán, a cop until her sudden unexplained resignation last year, was arrested three weeks ago on charges of impersonating a police officer after pulling a man over at a gas station in Miami and flashing a Miami-Dade police badge.

Monday, she did it again, police say — but her impersonation took a different turn.

This time, police said Alemán, 46, took advantage of a troubled woman by offering her counseling while pretending to be a police officer working on a cyber crimes and terrorism task force with the Miami-Dade police department.

The woman, whom police identified as Sara Rapkin, 21, said she actually met and received counseling from Alemán’s sister. Rapkin’s mother called police on July 30 after seeing Alemán’s face on television two weeks ago — after her arrest for impersonating a county cop during a traffic-jammed commute on Coral Way.

Alemán and Rapkin could not be reached Tuesday morning. State records show that Alemán remained jailed Monday morning at the Turner Guilford Knight Correctional Center. Her bond was set at $15,000.

Alemán was hired by Miami-Dade police in 2001 and worked in the Kendall, airport and Northwest districts until her resignation last year. Miami-Dade police wouldn’t comment on Alemán’s arrest or her sudden departure from the force.

“She voluntarily separated from the department,” Sgt. Carlos Rosario said.

According to her most recent arrest affidavit, Rapkin’s mother, concerned for her daughter’s well-being, spoke with her mechanic on July 21, who said he knew Alemán, a county cop who might be able to help her daughter.

Rapkin’s mother, Adriana Rapkin, made contact with Alemán three days later and was told Alemán was going to bring her sister — a psychologist — to the meeting. Alemán and the woman she claimed was her sister met with the Rapkins the night of July 24, the report says.

The Rapkins said Alemán left them a business card indicating she was a Miami-Dade police officer. Then, on July 27, Sara Rapkin had a counseling session with Alemán’s purported sister, a woman who went by the name of Silvia Trana. After the meeting, the Rapkins paid Trana $300.

Reached by telephone on Tuesday, Trana confirmed that Alemán was her sister. She also said she was a licensed mental counselor who was referred to and met with Sara Rapkin.

She also said she had no clue her sister had resigned from the Miami-Dade police department.

“I didn’t do anything wrong. Unfortunately, I didn’t know she resigned until I got worried and looked it up,” Trana said. “I broke into tears. I was not aware. I’m as clueless as you are.”

On July 30, Adriana Rapkin told police she saw a picture of Alemán on television and realized she was getting scammed. Police arrested Alemán on Monday.

The arrest was Alemán’s second in three weeks for impersonating a county cop. On July 27, police said, Alemán followed a man into a gas station on Coral Way after they exchanged words while stuck in a traffic jam. She flashed a badge, the man said, and believing she was a police officer, told her he did nothing wrong.

Miami cops soon showed up. When they asked Alemán for identification, they said she refused. Police charged her with impersonating a police officer and possession of a controlled substance after they said they found pills scattered in her car, in bottles that didn’t bear her name.
