Boston ( CNN ) -- An array of witnesses testified Friday in the 20th day of the federal trial of reputed Boston mob boss James `` Whitey '' Bulger : Former drug dealers , family members of alleged victims and a forensic dentist all took the stand . Some of Friday 's most interesting testimony came when former drug dealers detailed the scare tactics they said Bulger used , including extortion and shooting one of their brothers . Bulger is charged in the deaths of 19 people during some two decades when prosecutors say he ran Boston 's Irish mob . He also faces charges of extortion , racketeering and money laundering . The rules of the street . Paul Moore testified about the rules of the street when he was dealing drugs in Boston the early 1980s . Zach Hafer , assistant U.S. attorney , asked Moore whose permission he needed to sell drugs in South Boston . `` Jimmy Bulger , Whitey , '' Moore replied . To sell cocaine in South Boston , Moore said that and his partner , Billy Shea , had to pay `` rent , '' a weekly or monthly fee to Bulger and his gang . Rent payments to Bulger 's gang were between $ 3,000 and $ 5,000 . `` If you did n't pay , you 'd get hurt , '' explained Moore . Anthony Attardo , another former drug dealer , testified that he did n't pay `` the rent , '' and then failed to pay a $ 100,000 fine for the missing rent payments . Attardo 's brother was shot . `` What happened after he was shot ? '' Hafer asked . Attardo replied that Bulger and his long-time associated Kevin Weeks came to his house and said `` you 're next . '' Attardo said he gave Bulger $ 80,000 and Bulger told him not to worry about the rest . Families share their outrage in court . In addition to hearing about the crime world 's rules for drug dealing , the jury went on to learn about the heartbreaking loss the families of murder victims suffered . Steve Davis , the brother of Debra Davis , became emotional talking about his younger sister , whom he also called his best friend . Davis told the court his sister was dating Steve Flemmi , Bulger 's partner . One day , she just did n't come home . `` Did you ever see your sister again ? '' Hafer asked . `` Not until yesterday , '' answered Davis in reference to the pictures of her remains that were shown in court . As Davis was getting off the stand , he held a photo of his sister toward Bulger , who would not look up . Davis later told reporters outside the courthouse , `` I wanted recognition from him . He 's been sitting with his head down . '' Another relative of a victim , Patricia Donahue , spoke about the agonizing wait she endured to find out what had happened to her husband . Donahue told the court that while she was preparing dinner , she heard a TV news announcement of a gangland slaying -- and then she saw a picture of her father-in-law 's car , which she knew her husband had been driving . `` I called every single hospital in the Boston . '' Michael Donahue , who was not affiliated with any gang , was giving his friend Brian Halloran a ride home from a bar that night . Earlier in the trial , disgraced former FBI agent John Morris had apologized to Donahue 's family . Morris said that he leaked information to Bulger that Halloran was about to disclose details of Bulger 's gang . After court , Patricia Donahue spoke about testifying in front of Bulger . `` He could n't look at me . If he can kill people and not look victims in the face , he is a coward . '' Forensic dentist identified two bodies . Jurors also heard testimony from forensic dentist , Dr. Kathleen Crowley . She was able to positively identify the remains of two alleged Bulger victims . The specific details of the dental work that helped identify Arthur `` Bucky '' Barrett 's remains included a root canal , Crowley explained . Earlier in the week , Bulger 's long-time crime associate , Kevin Weeks , testified that he saw Bulger shoot Barrett in the back of his head after Barrett had tried to buy his way out of death . Using the same forensic methods , Crowley was able to determine that a different set of the remains belong to John `` Joey '' McIntyre . Weeks alleged that Bulger killed McIntyre after McIntyre admitted to letting authorities capture drugs that Bulger 's gang had intended to sell . So far the prosecution has called 46 witnesses . The prosecution expects to call 20 more witnesses , including Flemmi , and believes it could wrap up in 10 days . Thursday : Jurors view photos of alleged victims ' remains .
