Siemens Contract Employee Gets Jail Time for Intentionally Damaging Computers

For Immediate Release
U.S. Attorney's Office, Western District of Pennsylvania

PITTSBURGH - A contract employee for Siemens Corporation at the Monroeville, PA location has been sentenced in federal court to a six-month term of imprisonment to be followed by a two-year term of supervised release, and a fine of $7,500 on his conviction of intentional damage to a protected computer, United States Attorney Scott W. Brady announced today.

United States District Judge William S. Stickman imposed the sentence on David Tinley, 62, of Harrison City, PA.

According to information presented to the court, from in and around 2014 and continuing until on or about May 13, 2016, Tinley intentionally inserted logic bombs into computer programs that he designed for Siemens Corporation. The logic bombs ensured that the programs would malfunction after the expiration of a certain date. As a result, Siemens was unaware of the cause of the malfunction and required Tinley to fix these malfunctions.

Assistant United States Attorney Shardul S. Desai prosecuted this case on behalf of the government.

United States Attorney Brady commended the Federal Bureau of Investigation for the investigation leading to the successful prosecution of Tinley.
