No drugs were found during a routine, random drug dog scan Friday at Patterson Mill Middle/High School.
The scan, done as part of the school system's commitment to keeping illicit drugs out of the schools, was done using a police dog under the direction of the Harford County Sheriff's Office.
The dog sniffed 250 lockers in 25 minutes (8:45 to 9:10 a.m.), alerting once. No controlled dangerous substances or tobacco products were found when the locker was searched.
The scan was supervised by four Harford County Sheriff's Office deputies, one drug dog, four school administrators and the school system's coordinator of safety and security.
