The Pima County, Ariz., sheriff says a raid at a former Marine's Tucson-area home stemmed from a 20-month drug and homicide investigation.
Sheriff Clarence Dupnik (DOOP'-nik) told an Arizona Daily Star editorial meeting that details into Jose Guerena's activities will not be released because it could place an informant at risk.
Special Weapons and Tactics officers went to Guerena's house May 5 to serve a search warrant. Department officials say Guerena was killed when SWAT officers fired 71 rounds.
The Pima County Medical Examiner's Office says Guerena was hit 22 times and died at the scene.
Dupnik would not comment on the tactics used by the SWAT team and said a board made up of officials from each of the agencies involved in the shooting would review the case.
