A former Baltimore Substance Abuse Systems Inc. employee, who hacked into the chief executive's computerized presentation and replaced it with pornography, was sentenced Tuesday in Baltimore City's first computer hacking case, according to the city's state's attorney's office.

Walter Powell, 52, of the 3800 block of Frankford Avenue pleaded guilty to invading the computer system of his former employer.

Powell was fired from his job at the Baltimore Substance Abuse Systems in 2009 and began hacking into the computer network, including an incident in which he replaced a presentation to the board of directors with porn, according to a release from the city state's attorney's office.

Circuit Court Judge M. Brooke Murdock sentenced Powell to two years in prison with all time suspended, as well as 100 hours of community service and three years of probation.
