CASTANEA TOWNSHIP — A man has been arrested on child porn and child sex charges in central Pennsylvania.
Troopers say Michael Grenninger, 35, contacted who he thought was an 11-year-old girl and offered money in exchange for sex.
That 11-year-old girl was actually an investigator.
Police executed a search warrant on his property and found child pornography.
Grenninger is behind bars in Clinton County.
