Nina Marone of West Mifflin talks to the media next to five large images of 6-year-old Julian Hoffman on Thursday. A West Mifflin mother who was charged with child endangerment after her 10-year-old son shot and killed Julian, his brother, with her gun was ordered Thursday to stand trial. Kayleigh Potter, 29, faces four counts of endangering the welfare of children, illegally possessing marijuana and lying on the paperwork when she purchased the gun that killed Julian. Nina Marone is the great aunt of Julian. (Photo by Darrell Sapp/Post-Gazette) #Pittsburgh #PGH #412 #WestMifflin #PGPhotos
