The younger brother of the man behind the 2018 Parkland mass shooting was arrested in Virginia on Tuesday after deputies say he trespassed on multiple school properties after hours, trying to get inside.

Deputies in Virginia recently arrested the younger brother of Parkland school shooter Nikolas Cruz for allegedly trespassing at three schools. Investigators say Zachary Cruz, 24, was caught on security cameras trying to open doors.

Surveillance footage recovered from Jan. 25 showed him attempting to open exterior doors and peering into the schools.
