Investigators arrested a suspect, Leslie Allen Merritt Jr., on Friday. They believe he is connected to the first four shootings. That, however, leaves seven other incidents without a suspect, stoking fears of a copycat.
Dr. Marvene Lobato, the superintendent of the Fowler Elementary School District says she still worries for her students' safety.
"For our students, that’s just not enough," she said. "There are still seven [shootings] that we don’t have answers for."
