Boston ( CNN ) -- After deliberating for more than 20 hours over three days , jurors in the James `` Whitey '' Bulger trial wrapped up for the day Thursday afternoon and will be back at it for a fourth day on Friday . The eight-man , four-woman federal panel asked Thursday to see one of the pieces of evidence in the case -- a gun with an obliterated serial number . The last charge in the 32-count indictment accuses Bulger of possession of firearms with obliterated serial numbers . Bulger , 83 , is accused of racketeering , including involvement in 19 killings , and also 13 counts of extortion and money-laundering during a 20-year `` reign of terror '' that defined South Boston from the early '70s through 1995 , when Bulger fled Boston . Outside the courtroom , Bulger 's lead attorney , J.W . Carney , said he was `` very , very proud of the service these jurors have provided to us no matter what the outcome of the trial . '' Carney added that it was difficult waiting for a verdict `` because we invested at this point two years of work to get this case ready for trial . '' `` The longer the jury stays out the more it shows us they are as conscientious a jury as I have ever seen , '' Carney said . `` I know that the prosecutors also believe that , the judge believes that . We are very pleased at that . '' The widow of one of Bulger 's alleged murder victims said separately that she believed `` the jurors are looking at the situation and trying to do right by all of us . '' Patricia Donahue , who has been at the trial almost every day with her three sons , added , `` We been putting our lives on hold since this trial started -- it 's tough ... but it 's almost over now . '' Still , Donahue said , `` If deliberations go for a long period of time I 'm going to start to worry about a mistrial . '' 'You 're a coward ! ' widow yells at Bulger . On Wednesday , jurors submitted five questions for the judge . One of the questions involved the second count of the federal racketeering charge , with that lengthy count including numerous alleged acts and involvement in killings . Jurors wanted to know whether they needed to vote unanimously on the 33 `` predicate acts , '' including the 19 murders . U.S. District Court Judge Denise Casper answered in the affirmative , although she advised jurors that if they were unable to reach a decision on a specific act , they can move on and decide the next act . For Bulger to be found guilty under that racketeering count , one of the major charges against him , jurors must agree that prosecutors proved he committed at least two of the acts within a 10-year period . During the seven-week trial , jurors heard dramatic testimony from convicted gangsters , bookies , extortion victims , a disgraced FBI supervisor , ex-drug dealers , retired FBI agents and relatives of people Bulger is accused of killing . Prosecutors called 63 witnesses . The defense called 10 . Former hit man John Martorano testified for both sides , for a total of 72 witnesses over 35 days . Bulger never took the stand despite repeated hints from his lawyers throughout trial he would testify . In fact , Bulger seemed to want to testify . Questioned by Judge Casper , Bulger called his decision a `` choice made involuntarily . '' Bulger was a fugitive for more than 16 years , disappearing after a crooked FBI agent told him he was about to be indicted on federal racketeering charges . The FBI tracked him down and arrested him in 2011 in Santa Monica , California , where he had been living with his girlfriend under an alias . Bulger 's attorneys release photos designed to show his softer side .
