Dubuque police on Tuesday investigated the second reported threat in as many days at Hempstead High School, finding no evidence of dangerous materials either day. At around 6:45 a.m. Tuesday, the Dubuque 911 Center received a call reporting “specific threats of violence” at the school. On Monday, officers received a call just after 11 a.m. reporting a threat of a “possible explosive device” outside the school. According to a report, the school moved into an external lockdown, and after an investigation, Dubuque police and fire department officials determined that there were no dangerous items on campus. There was an increased police presence at Hempstead during the day on Tuesday, but the school was not on an exterior lockdown and classes proceeded as scheduled. The Police Department is actively investigating the phone calls.
