A jury found John Morgan Campbell, 66, guilty of 48 of the 53 counts against him Wednesday, WOAI-TV reports. His sentencing is set for December.

Prosecutors said Campbell — a former vice president of H-E-B and one of the creators of Central Market — sent a business-related email to a co-worker with a pornographic image of a boy mistakenly attached in April 2014. The photo was presented in court to the jury.

The co-worker told a prosecutor that he was shocked when he received the photo from Campbell.

He said he immediately went to his supervisor, who then brought it forward to human resources and police. The company fired Campbell, KSAT-TV reported.

When confronted by a corporate executive, Campbell didn't deny what he had done, a prosecutor told the jury. Instead, he said, "You got me," KSAT reported.

Texas Rangers seized Campbell's work devices and found 50 graphic images and three videos, according to testimony.
