Venice, Florida -- A Venice woman got the scare of her life last September when deputies swarmed into the floral shop where she works.

30-year-old Angela Silva tells 10 News she was working in arrangements for a funeral when she was approached by the deputies with very confusing news for her.

They told her they had a warrant for her arrest for allegedly selling a controlled substance to undercover detectives in July.

"I was very confused and scared. I had no idea what was going on," she said.

She knew she didn't do it and even had an alibi, because she was at work at the time of the alleged undercover sale. She says she has the time card to prove it.

Still, detectives carted her off to the Sarasota County jail anyway, and booked her on the charges.

Four months later, the charges were dropped and the Sarasota County Sheriff's Office was issuing their apologies.

Sheriff's Office spokeswoman Wendy Rose could not comment on the case because it is now part of an Internal Affairs investigation, however, she said they are taking what happened very seriously.

Rose confirmed this is a case of human error and misidentification.

Turns out, Silva has a similar name and appearance as a woman seen in the video taken during the sting. The video was provided to 10 News by Silva's attorney, Jordan Tawil.

When Silva saw the video for herself, she says it made her angry and still does to this day.

"Astonished, first of all," she said of her first reaction to the video, "How they could get two different people so mixed up and very angry actually that I had to go through something like this for no reason at all."

Arrest reports show a confidential source informed the narcotics detectives that a woman who goes by the name CIRA was selling Roxicodone pills in the Venice area.

The reports tell the rest of the story: the source set up a buy for the undercover detectives that same day on July 21, 2010.

The detective wrote in his report: "Through investigative means, I was able to determine that Cira was Angela Marie Silva..."

The source then positively identified Silva and the deal was set up over the phone. The report says the woman on the other end of the line agreed to meet them that day to buy Oxycodone pills for $100.

The undercover video shows a buy did go down, but there's a big problem with the detectives' case.

The woman in the video is not Silva and yet, they pursued a case against her without questioning her prior to her arrest, and did not even use their own sources to check a previous booking photo to confirm it was the right person, according to Tawil.

Silva has a prior arrest for DUI, according to arrest records.

"We have drafted notices of intent to sue, but we're hoping the sheriff's office can conduct their own investigation, make a recommendation and I'm hoping that will satisfy Ms. Silva's claims and there won't be any need for a lawsuit," explained Silva's attorney, Jordan Tawil.

In January, the case was dismissed by the State Attorney's Office.

But, the pain and embarrassment of what happened still stings for the young woman as does the record of the arrest which she also hopes to get expunged.
