ROCHESTER, N.Y. (WROC) – A Rochester Man and prior sex offender is facing prison time after he was convicted on new child pornography charges. Gregory Pum, age 49, was previously convicted of Sexual Performance by a Child less than 16-years-old and was sentenced to serve six months in jail followed by 10 months' probation in 2014. Pum was discharged in May 2016. In May 2022, law enforcement received two cybertips from the National Center for Missing and Exploited Children that a user of an email account belonging to Pum had uploaded 29 images and video of child pornography to a file sharing site. Investigators later received seven additional cybertips related to the same email account. In June 2022, a search warrant was executed at Pum's house where officials found electronic devices that contained images of child pornography. On March 11, 2024, Pum was on pretrial release when law enforcement executed another search warrant at his home after receiving two additional cybertips and found 19 images and one video of child pornography on an iPhone. Pum was convicted of possession of child pornography by an individual with a prior sex offense conviction. He was sentenced Tuesday to serve 10-years in prison and 10-years supervised release.
