A 77-year-old Tecumseh man convicted at a May jury trial of aggravated possession of child pornography was sentenced Wednesday to serve 20 years and prison and pay a $25,000 fine.

Philip Jan Cannon appeared in Pottawatomie County District Court for formal sentencing.

First Assistant District Attorney Adam Panter said Cannon stood trial back in May on a single count of aggravated possession of child pornography, with the case involving about 1,500 photographs of evidence.

The jury, after announcing their guilty verdict, recommended the maximum sentence and fine — 20 years in prison and a $25,000 fine.

District Judge John Canavan followed the jury's recommendation Wednesday, with Cannon receiving the maximum sentence and fine.

The defendant, at 77-years-old, will spend the rest of his life behind bars.

“I requested the court, on behalf of his victims and for being able to hide his crimes for so long, to ensure that he dies in prison,” Panter said.

Cannon was originally arrested in 2016 after obscene photographs of young girls were found at a warehouse building he owned in downtown Tecumseh.

The Oklahoma State Bureau of Investigation was originally asked to investigate the case after allegations were made about images being found by a person hired to work on the buildings.

During a search, agents collected evidence including printed color and black-and-white pictures showing what appeared to be underage nude females.

The photos confiscated in the case included random photos that were printed as well as photos taken from as far back as the 1950s and 60s, Panter said, along with digital images found on a computer.

A count of felony child sexual abuse that was originally filed with the 2016 case was dismissed back in March, court records show.

Cannon will remain jailed in the Pottawatomie County Public Safety Center until he is transferred to the Department of Corrections.
