( CNN ) -- A 69-year-old Massachusetts man was arrested and charged Friday in Boston in connection with the death of Stephen Rakes , a regular at James `` Whitey '' Bulger 's trial before he was found dead last month near a walking trail , authorities said . William Camuti was taken into custody in Boston and charged with attempted murder , misleading police and unlawful disposition of human remains , the Middlesex District Attorney 's office announced in a press release . His attorney could n't be immediately reached for comment . The body of the 59-year-old Rakes was found July 17 in a wooded area in Lincoln , Massachusetts , about 30 miles from his home in Quincy . Rakes had been an alleged extortion victim of Bulger 's , and had learned shortly before his death that prosecutors no longer planned to call him to testify , according to a friend . Bulger , a reputed Irish mob boss in south Boston , is now standing trial in that city for allegedly participating in 19 murders , racketeering , money laundering and extortion over a two-decade period . Widow yells at Bulger after he wo n't take the stand . Camuti and Rakes were longtime business associates , and Camuti allegedly poisoned Rakes at a time when Camuti owed money to Rakes . `` We allege this defendant intentionally put poison in the victim 's iced coffee and then disposed of his body , '' Middlesex District Attorney Marian Ryan said in a statement . In a phone call on July 16 , Camuti asked Rakes for a meeting to discuss a potential investment property in Wilmington , Massachusetts , authorities said . In fact , the investment deal was fake , authorities said . On the same day , surveillance video showed Rakes leaving the federal courthouse where he regularly attended Bulger 's murder trial . Rakes appeared to be wearing the same clothing in which his body was found , authorities said . The two men met that afternoon in a McDonald 's in Waltham , and Camuti bought two iced coffees , one of which he allegedly laced with two teaspoons of potassium cyanide and gave to Rakes , who drank it , authorities said . Camuti allegedly drove Rakes around the cities of Waltham , Woburn , Burlington and Lincoln for several hours . Investigators alleged Camuti dumped Rakes ' body in the wooded area , where it was found the next day . The medical examiner 's office has yet to determine the cause of Rakes ' death , authorities said . CNN 's Michael Martinez and Greg Botelho contributed to this report .
