MUSKOGEE, Oklahoma - A former Muskogee firefighter will be sentenced in April after pleading guilty Monday to possession of child pornography, sexual abuse of a child and other charges.

The investigation began after a woman told the sheriff's office that 31-year-old Zackery Perry asked for photographs of her child.

The Muskogee Fire Department put Perry on administrative leave during the investigation.

Melissa Skelton, 26, of Muskogee who was also arrested during that investigation, pleaded guilty to related charges and was sentenced to prison in September 2017.
