WHITE DEER TOWNSHIP -- A fourth teenager has been charged with a rock throwing incident in Union County that seriously injured a woman.
Authorities say Keefer McGee, 17, of New Columbia was charged Monday as an adult with aggravated assault and other counts.
Police say McGee and three others threw a rock off an overpass along Interstate 80 near Milton last month.
The rock smashed through a windshield, injuring Sharon Budd of Ohio.
Officials at Geisinger Medical Center near Danville said Budd's condition had been upgraded to serious.
