The District Attorney’s Gangs Division prosecutes the most serious gang crimes committed in the county. This division is a vertical prosecution unit, which combines Deputy District Attorneys with District Attorney Investigators to handle the unique and dangerous issues that arise in gang prosecutions. Led by Division Chief Dana Greisen and Assistant Chief Frank Jackson, the division’s staff is some of the finest in the nation.
Last year, the Gangs Division continued its proactive role with local, state, and federal law enforcement. Prosecutors and investigators participated on numerous task forces targeting gang members and the crimes they commit.
The Gangs Division continues to participate in targeted operations, which have been highly successful in addressing gang crime in San Diego. This zero-tolerance approach disrupted some of San Diego’s most violent gangs and resulted in convictions for charges including robbery, carjackings, drug sales, witness intimidation, armed assaults, drive-by shootings, and murder. As a result, gang homicide rates in San Diego are below the average of the last two decades and remain well below historic levels below that of most major metropolitan cities.
Another area of gang suppression is the Border Crimes Task Force, which was founded in 2009 through a federal grant. Two investigators are assigned to the task force. Along with federal and state law enforcement, the task force combats violent crime including murders, kidnappings, robberies and narcotic trafficking associated with major Mexican drug cartels. This task force coordinates efforts of law enforcement and prosecution to effectively combat the growing threat of serious and violent crime occurring in San Diego as a result of drug cartel influence in Mexico.
While there are hundreds of success stories in this division, the ongoing seriousness of gang violence in San Diego is reflected by the kinds of cases and defendants prosecuted in 2015.
