I hate to see this: FDLE begins investigation in undercover cop's death ORLANDO, Fla. Authorities sought to determine Sunday what happened before a college football game when a University of Central Florida police officer was fatally shot by another officer outside the Citrus Bowl. A third person, not identified by authorities, remained hospitalized Sunday with a gunshot wound, officials said. Mario Jenkins, a canine officer who had been working with state Division of Alcoholic Beverages and Tobacco agents to curb underage drinking, died after being shot Saturday by a retired Orlando police officer working on reserve status. The officer who fired the fatal shots, Dennis R. Smith, was placed on administrative leave, Orlando Police Department spokeswoman Barbara Jones said Sunday. Smith retired after 25 years in December of 2001. Witnesses said the undercover officer broke up a gathering of students, who resisted his efforts. The officer then fired three shots into the air for help. Another officer saw a gunman, the undercover agent who was dressed in street clothes, and shot him several times. The Florida Department of Law Enforcement is handling the case, but had no new information Sunday. "Right now we're still in the very beginnings of the investigation," said FDLE spokesman Geo Morales, adding the agency is required to have any investigation involving police in fatal shootings completed within 60 days. Morales said the injured person was part of the investigation. That individual was not identified by FDLE.
