A Pottstown man convicted of putting spyware on his father's computer to capture passwords to e-mail accounts was sentenced Wednesday to two years' probation.

Parth Ingle, 25, installed the program in an effort to find out if his father, Arunkumar, was having an affair. The elder Ingle was later found slain, a crime that remains unsolved.

Parth Ingle also was given 80 hours of community service and ordered to pay court costs.

In 2008, Arunkumar Ingle, 55, was found dead by his wife in the bedroom of their Middletown Township home in Delaware County. The Boeing Co. engineer had been beaten and stabbed.

Parth Ingle, who had a contentious relationship with his father, and his sister Avnee, 28, were charged with wiretapping and intercepting e-mails. Avnee Ingle was acquitted at trial.

Parth Ingle installed the eBlaster software out of a desire to help his mother, Bhavnaben. The e-mails revealed that Arunkumar Ingle had been having an affair with a Philadelphia woman, Anna Sudakevich, since 2003. Parth Ingle also installed a GPS device on his father's car.

Sudakevich testified that she was unaware Arunkumar Ingle was married until Parth Ingle came to her home to confront his father. She also testified that Arunkumar Ingle was planning on getting a false passport, faking his own death, and moving with her to India.
