Computer Crime Investigations

This digital era has posed law enforcement with technology crimes that did not exist only a few decades years ago. The Mount Vernon Police Department has a fully trained investigator who specializes in the area of computer-based crimes. Be it online crime, or the computer being used as a tool to commit the crime.

Because of the unique nature of on-line crime, these types of cases are often difficult to investigate and time consuming. In many cases investigators in several Departments work together to solve these types of crimes because of the broad range of victims and cross jurisdiction involved.
