A former health and human services manager at the Philadelphia Office of Emergency Management, already awaiting trial on child pornography counts, was charged Thursday with distribution of child porn after another search of his South Philadelphia home, federal prosecutors said.

Grant Shea, 30, of the 2000 block of South Dorrance Street, was charged last year with receipt, possession, and distribution of child porn, and was released to home confinement pending his trial.

Investigators, however, suspected that Shea was again getting involved with child porn and on Jan. 30 executed a search warrant at his residence, and found child porn on his cellphone, according to court documents.

On Thursday, Shea was charged with receipt, possession, and distribution of child pornography. He previously was charged only with possession in the new case.

He faces a maximum of 60 years in prison and a mandatory minimum of five years.

Shea began working for the Office of Emergency Management in May 2012 and served as health and human services program manager from March to July 2016, when he resigned.
