Boston ( CNN ) -- With only a half-dozen witnesses to go , lawyers for James `` Whitey '' Bulger have still not confirmed whether the reputed mob boss will take the stand on his own behalf . The delay has frustrated prosecutors who Wednesday told the judge they have the right to know whether they should be working on cross-examination or closing summations . On Day 33 of the federal racketeering trial , defense lawyers continued to raise questions about what the FBI did and did not do to prevent some of the murders Bulger is accused of committing , among them the death of Bulger crime associate Brian Halloran . Retired FBI Agent James Crawford testified that 10 days before Halloran and his friend Michael Donahue were murdered , he was approached by a woman described as having a `` close relationship '' with Steven `` The Rifleman '' Flemmi , Bulger 's crime partner . Defense witness criticizes FBI 's inaction on Bulger . The woman insisted on total anonymity knowing she 'd be killed if Flemmi found out , telling the agent there were people in law enforcement on the Bulger payroll . The confidential informant told Crawford `` Flemmi was going to kill Halloran for being a snitch . '' Crawford gave her his word he would not put it in writing . However , he did speak with a supervisor who said the information should be `` put on a back burner . '' Ten days later Halloran was dead . The woman , believed to be Olga Davis , later approached the FBI agent asking for help finding her daughter Debra Davis who had disappeared . Debra was Flemmi 's live-in girlfriend . During the trial , Flemmi testified he lured her to a home where Bulger strangled her . Defense lawyers plan to recall hit man John Martorano to testify Flemmi admitted `` accidentally '' strangling the stunning 26 year old . The defense also plans to show that Flemmi , not Bulger , had motive to kill Deborah Hussey . Hussey 's mother , Marion Hussey , testified at a deposition that Flemmi called his common-law step-daughter a `` slut , a whore , a prostitute ... doing drugs . '' Also on the stand , retired FBI informant-coordinator Fred Davis . He testified that when he arrived at the Boston field office in the late 1970s there was a lot of `` paranoia '' in the bureau . `` They were nervous other agents in the office were leaking information . '' Key among the suspected leakers was Bulger handler John Connolly who would `` show up in my squad all too often , '' said Davis who was also in charge of electronic surveillance . `` A lot of my agents began to say he was up to no good , '' said Davis , testifying that Connolly had access to all the FBI files . When asked why he did n't alert his superiors , Davis said `` I did n't have enough specific information ... so I handled it man-to-man , so to speak . '' 'Threats ' described in trial . Davis said he was out with Connolly and other agents one night and did n't have enough money for tolls . Connolly apparently gave him $ 20 with the message , `` Agents in Boston should never want for money . '' Davis also reviewed Bulger 's FBI informant file and found the quality of information `` worthless . '' Davis says he felt Bulger should have been terminated as an informant , but did n't aggressively pursue it with his superiors or anyone at FBI headquarters in Washington . Soon after openly questioning the quality of Bulger 's information , Davis testified that corrupt FBI supervisor John Morris , who was on the Bulger payroll , moved the top-echelon files closer to his Organized Crime Squad . Davis could not confirm whether the Bulger file that he had in his hands was the one he reviewed more than 30 years ago saying , `` This file represents a lot more than what I saw . '' Prosecutor Fred Wyshak seemed to take offense at the suggestion it was a different file : `` Is it your testimony that this is NOT Mr Bulger 's file , '' he asked incredulously . Wyshak explained that Bulger 's file had been temporarily closed between 1978 and 1979 when Bulger was the target of an investigation and therefore not eligible to be an informant . Opinion : Just do n't call Whitey a rat . CNN 's Ross Levitt contributed to this report .
Defense says a Halloran criminal partner was the one who wanted informant dead . Testimony comes after other former Defense agents testify about Ten days later Boston FBI corruption . Flemmi faces murder , other charges in a 32-count indictment .
