( CNN ) -- The 911 call is accusatory . The woman flatly tells the dispatcher she just witnessed several police officers in East Bakersfield , California , beat a man to death . The woman -- identified by the local newspaper as Salina Quair , 34 -- happened upon the scene as she left Kern Medical Center , where the father of four would later die . `` There 's a man laying on the floor , and your police officers beat the sh-t out of him and killed him , '' said Quair , according to a tape of the 911 call obtained by CNN affiliate KERO-TV . `` I 'm right here on the corner of Flower and Palm right now and you have one , two , three , four , five , six , seven , eight sheriffs . The guy was laying on the floor , and eight sheriffs ran up and started beating him up with sticks . The man is dead laying right here , right now , '' she continues . The sheriff 's office has named the seven deputies involved in the incident , including a sergeant , while the California Highway Patrol has yet to name its two officers who responded to the scene . The area is largely residential , packed with one-story homes and small apartment complexes . In addition to the hospital , East Bakersfield High School and the county coroner 's office are within two blocks of the intersection where David Sal Silva died . The Kern County Sheriff 's Office has said it will not comment until the investigation is complete , but a news release says the incident began May 7 just before midnight . A deputy responded to a call that a man , later identified as Silva , 33 , was lying on the ground , possibly intoxicated . Silva was `` uncooperative , '' according to the sheriff 's office , even after a canine was deployed . `` The suspect continued to actively resist the deputy and the K-9 . Additional deputies arrived on scene , along with two CHP officers who responded to assist . The suspect continued to resist and received baton strikes from the deputies attempting to take him into custody , '' according to the sheriff 's news release . After Silva was restrained , police requested medical assistance for his injuries , the release said . He was having trouble breathing and was taken across the street to the hospital . `` While being treated at KMC , the suspect was pronounced dead at about 12:44 a.m. , '' the news release said . Several witnesses have painted a more brutal picture , saying that Silva was crying for help and officers continued to beat him until he fell silent . Others have said they captured the incident on their cell phones . Two of those witnesses hired attorneys after police confiscated their phones , KERO reported . In a news release Tuesday , the Kern County Sheriff 's Office said that Youngblood has requested the FBI 's help in analyzing `` two cell phones pursuant to a search warrant related to the ... death of David Silva . '' It was not immediately clear which phones these are or what `` forensic analysis '' is being done , though the office did say that Bakersfield police saw one of the phones on video from the incident , but not the other one . Youngblood also asked the FBI to conduct a `` parallel '' investigation into the incident . `` I think it 's the right thing for the public , and I think it 's the right thing for this organization , '' the sheriff told reporters Tuesday . The only video released thus far is from a security camera , and the quality is poor . It appears to show two men scuffling for about two minutes before another man arrives . The two men appear to repeatedly hit the third man as he 's on his knees and later lying on the ground . Police cars arrive and officers gather around the man on the ground , but their actions are n't clear . The video is grainy , and the blur of light and shadows makes it difficult to determine what is happening . Witnesses told CNN they were awakened by the incident . One witness , who asked not to be identified , described a chaotic scene . `` He was asking for help . He was screaming with pain . He only got to ask for help like three times , '' he said . `` Those hits were brutal . '' Sheriff Donnie Youngblood promised a fair investigation into the incident . `` I 'm waiting till this investigation is done so I can look at it objectively and decide whether we did something wrong , and If we did , I 'll stand up and tell you that we did . If we did n't , I 'll stand up and tell you that we did n't , '' he told KERO . In November , the family of Jose Lucero , 33 , won a $ 4.5 million civil judgment against the Kern County Sheriff 's Office , according to The Bakersfield Californian . After the mentally ill Lucero had made delusional 911 calls , four deputies beat , pepper-sprayed and Tasered him , killing him in front of his parents , according to the newspaper 's report about the 2010 incident . CNN 's Eliott C. McLaughlin and Stephanie Elam contributed to this report .
