Boston ( CNN ) -- Graphic testimony from a forensic anthropologist , including images of decomposing bones and brain matter , continued Thursday in the federal case against Boston 's reputed mob boss , James `` Whitey '' Bulger . Dr. Ann Marie Mires , a Massachusetts state forensic anthropologist , showed jurors gruesome photos of human remains found in shallow graves in the Boston area . One grave was at Tenean Beach in Dorchester , and two sets of remains were excavated along the Neponset River . The remains at Tenean Beach were found in a 3-foot grave in September 2000 , Mires told the court . Jurors were shown several photos of the remains there , including parts of a pelvic bone , a fractured skull with decomposed brain matter and a claddagh ring with part of a decomposed finger bone . Earlier this week , Kevin Weeks , Bulger 's longtime crime associate , told jurors that at this location , Bulger said , `` Drink up , Paulie , '' in reference to Paul McGonagle . Authorities believe Bulger killed McGonagle , who was a leader of a rival gang in Boston . Expletives fly between Bulger and ex-partner . Most of McGonagle 's remains were severely decayed due the shallow grave and the corrosive damage from the water , Mires explained . Some of his remains were very much intact , though . Jurors were shown a picture of a pair of shoes , socks and leg bones extending straight out of the socks . 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 . Two set of remains that were found along the Neponset River had also been damaged by water and tidal currents , Mires said . The first set of remains was excavated there in late September 2000 , and it included part of a skull with a bullet hole , she said . The remains were found with a bulletproof vest , a navy , three-piece suit , driving gloves and a claddagh ring around a finger bone . Mires testified that these were the remains of Thomas King . John Martorano , one of Bulger 's hitmen , testified earlier in Bulger 's trial that Martorano himself shot King in the back his head , and he knew where King 's body was dumped . `` I was driving over Neponset Bridge ( in Boston ) one day , and Whitey said , 'tip your hat to Tommy ... . He 's over there , ' `` Martorano testified . The remains of Debra Davis were discovered about a month later along the river . Most of her remains were discovered in plastic bags along with rope around the bags , Mires explained . Almost all of Davis ' bones were recovered . Because her body was in bags , even some of her hair was preserved . Mires showed the jury photos of the remains , the hair found on the skull , and how the tidal movement corroded Davis ' skull . Her hair , along with pieces of her bones , were tested for DNA and were positively identified as the remains of Davis , according to Mires . One of the shortest and more emotional testimonies of the day came from Elaine Barrett , the widow of alleged Bulger victim Arthur `` Bucky '' Barrett . Earlier in the trial , 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 . `` He called at 11 , said he would n't be home for a while ; he had to get money , '' Elaine Barrett told the court . `` Did your husband , Bucky Barrett , ever come home ? '' Assistant U.S. Attorney Fred Wyshak asked the widow . `` No . '' Barrett answered , tearing up . She said she never saw or spoke to her husband again . Earlier in the day , before the jury entered the courtroom , the judge heard a request from J.W . Carney , Bulger 's attorney , to postpone the trial until next week . He said the defense team needed more time to go over the materials and evidence and that Bulger , 83 , was tired . Bulger imitates machine gun , talks about a killing in recorded jail visit . Assistant U.S. Attorney Zach Hafer argued against the motion , telling the judge that the victims and their families have waited long enough for justice and the defense had enough time to go over the materials . U.S. District Judge Denise Casper dismissed Carney 's request . Thomas Donahue , a son of one the alleged Bulger victims , told reporters outside of court on Thursday , `` I do n't care if he ( Bulger ) is tired , '' in response to Carney 's request . `` Like it was said in court he ( Bulger ) had 16 years to relax ... He will be fine , '' said Steve Davis , brother of Debra Davis . Bulger 's trial continues Friday when the prosecution plans to call a forensic dentist as well as Steve Davis .
