The Jim Hogg County Sheriff's Department is reaching out to surrounding counties for help finding a man who triggered a school lockdown this morning. An unidentified man reportedly went by the Hebbronville Junior High School, looking for a student not listed in the school. He was confronted and asked to leave. A bomb-sniffing dog was used to check the area as a precaution. Officials say they don't believe the man is in the Jim Hogg County area anymore, but have passed along their information to surrounding counties to help find him.
