Police and school officials are investigating after a central Pennsylvania high school student sent her mother an April Fools' text about a shooting -- only to have the mother call 911.
State College police say officials quickly determined the text was meant to be a joke.
But before that happened Wednesday, seven officers joined a school resource officer and the school district and police began following a planned response to a school shooting.
