Fla. Cops Under Fire After Informant's Murder

McCranie said he was not sure why a gun was involved in the deal. He also said that Hoffman, as a confidential informant, had received some instructions, which he declined to describe, but not necessarily training.

"We're asking her to do what she already does," he said. "She's involved in the drug trade. She's already familiar with how to act in these cases."

In addition to the 2007 drug charge, authorities also released information about an underage drinking charge Hoffman faced in 2003, as well as multiple instances in which she was targeted by thieves -- crimes he said are often related to drugs.

"They're basically pointing the finger at Rachel," said Devine, who served as Hoffman's attorney after the 2007 bust, in an interview with ABC News. "What does her underage drinking charge have anything to do with what happened to her?"

Hoffman wanted to know why, as her attorney, he did not know about this offer from police -- something McCranie said was not uncommon.

"They're asking her to do something that would put her in a life or death situation," Devine said. "I have never had any time where the police department has not called me to tell me this is what's happening."

Further, Devine said, Hoffman did not have any previous experience with firearms, but authorities knew from the terms of the deal that she would be confronted by a pair of men -- one of whom had a violent criminal past -- who were carrying at least one gun.

"She had never worked as an undercover agent," he said. "She had no experience or training in this matter."

Finally, Hoffman challenged police reluctance to at least share with her family members some details from the murder scene to allow them to grieve.

"They are left to speculate and guess about the cause of her death," he said. "Was she tortured? Was she beaten?"

While the police continue to defend the decisions that drew Hoffman into her role as an informant, even William "Willie" Meggs, the state's attorney in Tallahassee who will ultimately prosecute Green and Bradshaw, said that his office should have known about the April raid at Hoffman's apartment and her subsequent deal with authorities.

"We would have liked to have known and we did not," Meggs told ABC News, stressing that as a participant in the drug court, Hoffman already had a relationship with a case worker in the program and should not have any kind of drug interaction involving police without his office knowing.

Sandi Copes, a spokesman for Florida Attorney General Bill McCollum, confirmed to ABC News that his office will conduct an independent review of "internal policies and procedures" used by the Tallahassee police involving informants.

McCranie, who repeatedly said that Hoffman is the victim of a murder, said that when the investigation is complete, two killers will be charged with murder and the public will see that the Tallahassee Police Department did its job.

"Rachel made some mistakes, but she is the victim," he said. "What killed her is Green, Bradshaw and drugs. That's what killed Rachel."
