McCarthy, who had spent just two years on the force before the incident, told police investigators that he feared for his life before he shot Ortega. Based on the officer’s version of events, prosecutors said Ortega’s killing was justified.
“But police reports, depositions, interview transcripts and other evidence disclosed in a federal lawsuit filed two years ago by Ortega’s widow reveal inconsistencies in McCarthy’s account of what happened in the alleyway immediately before Ortega’s death. U.S. District Court Judge Larry Burns, who is presiding over the case, recently expressed doubt that it would be possible for McCarthy to have done everything he said he did during his altercation with Ortega.”
