The Los Angeles County District Attorney’s Office has the largest local prosecutorial unit dedicated to computer-related crime in the nation and has been an international leader in the prosecution and investigation of high-technology crime.

District Attorney Jackie Lacey has worked to enhance the office’s Cyber Crime Division. One of her administration’s top goals is to increase efforts to investigate and prosecute identity thieves and high-tech criminals. 

Toward that goal, the office forged new partnerships with businesses and the banking industry to combat fraud. Two gasoline retailers, Chevron and Shell, implemented new protocols and added better security measures to prevent criminals from installing devices that allow the theft of credit and debit card information. City National Bank has aided criminal investigations by sharing information about fraud activity and showing where vulnerabilities may exist.

District Attorney Lacey hosted the office’s first High Tech Fraud Symposium and has worked to improve the office’s training programs to find ways to stop cyber-crimes.

District Attorney Lacey also is helping consumers take steps to make sure they are not victims of identity theft. Read more about ID theft.

Cyber Crime Division prosecutors are specially trained to handle computer-related crimes. Investigators assigned to the High Technology Crime Unit operate a forensic laboratory that features a state-of-the-art clean room and electronic evidence vault.

The office’s prosecutors and investigators have become internationally recognized leaders who have trained thousands of criminal justice professionals throughout Los Angeles County, California and the United States. Whenever there is an attack on Los Angeles County’s computer infrastructure, the District Attorney’s Cyber Investigation Response Team has been tapped to resolve security breaches. The squad responded to an increasing number of cyberthreats on the county’s computer network.
