( CNN ) -- The word Friday on a homicide investigation into the death of a man whose body was found less than a mile from the home of Patriots tight end Aaron Hernandez was the same from authorities and from Hernandez -- no word at all . Hernandez has yet to say anything publicly . Instead , a statement from his lawyer acknowledged there was an investigation , but did n't confirm media reports that authorities had questioned his client . `` It has been widely reported in the media that the state police have searched the home of our client , Aaron Hernandez , as part of an ongoing investigation , '' attorney Michael Fee said . `` Out of respect for that process , neither we nor Aaron will have any comment about the substance of that investigation until it has come to a conclusion . '' Three search warrants have been issued in the case , according to North Attleborough , Massachusetts , criminal clerk magistrate Mark Sturdy . They have not been made public yet because the files have not been returned , and Sturdy would not comment on whether they involved Hernandez 's house or property . The 27-year-old Lloyd , a semi-pro football player , was found dead less than a mile from Hernandez 's expansive home in North Attleborough . Police searched the home and sifted through the nearby woods this week for clues . Two investigators wearing Massachusetts State Police jackets , at least one of them carrying paper work drove up the driveway Hernandez ' house Friday , rang the front doorbell and a female let them into the home . They were in the home for a few minutes and then left . It was not clear what the investigators were doing and they made no comment when they drove away . Lloyd died of a gunshot wound , a law enforcement source with knowledge of the investigation said Thursday . Lloyd 's sister , Olivia Thibou , told CNN that Lloyd and Hernandez were friends and were at a Boston nightclub together Friday night . She said her brother was dating the sister of Hernandez 's fiance . She did not know when or how her brother and Hernandez met . Thibou said she did not know of any problems between Hernandez and Lloyd , who worked for a landscaping company . She ca n't imagine why anyone would want to kill her brother , whom she described as a friendly guy who was like a father to her 7-year-old daughter . `` My son is a wonderful child , '' Lloyd 's mother , Ursula Ward , said . `` He 's a family guy . He has not done anything to hurt anyone . '' Neighbors told CNN that Hernandez , 23 , has been a quiet , respectful neighbor . Hernandez , who is rehabbing a shoulder injury , returned to the house Wednesday afternoon wearing a gray Patriots sweatshirt and blue sweatpants . He did n't acknowledge the presence of the media and appeared to spend the rest of the day inside or on the back deck . But the investigation has already cost him at least one endorsement deal . CytoSport says it pulled its endorsement deal with Hernandez , effective immediately , because of the investigation . On the street between the home and where Lloyd 's body was found , police searched through tall grass . Nearly a dozen Massachusetts state police officers entered Hernandez 's home Tuesday evening , CNN affiliate WCVB reported . Patriots spokesman Stacey James said Tuesday the team was aware of the reports but would n't comment during an ongoing police investigation . Hernandez has played three seasons for the Patriots , averaging 58 catches per year . He was selected for the Pro Bowl in his second season . ESPN reported he signed last year a contract extension that would pay him $ 40 million for the 2014-18 seasons . North Attleborough is about 15 miles from Gillette Stadium , where the Patriots play their home games . As the mystery was unfolding in Massachusetts , Hernandez and his attorneys were dealing with a lawsuit in Miami in which a man claimed Hernandez shot him after they rode in a car after an argument at a strip club . According to a court document , Alexander Bradley contends he lost his right eye because of the February incident . The case was dismissed Monday over an error in the initial paperwork , but it was refiled on Wednesday , according to court documents . CNN 's Mary Snow , Lawrence Crook , and Susan Candiotti contributed to this report .
The investigation has already cost Hernandez at least one endorsement deal . A source told the Daily News that Hernandez's former agent, Drew Rosenhaus, is now working with a new agency, and he will not be involved in any future negotiations. Police searched area between Hernandez 's home and where victim 's body was found . The player signed a multimillion-dollar contract extension in 2012 .
