A former New Hampshire police officer has lost his certification after pleading guilty to fabricating traffic warnings and misusing driver records. The attorney general's office says Ryan Milligan, who resigned from the Merrimack Police Department, voluntarily surrendered his certificate and agreed to not seek future employment as a law enforcement officer as part of his plea agreement. The 36-year-old was accused of using state police data to write up fake warnings he claimed to have issued during a traffic enforcement assignment. He pleaded guilty to two misdemeanors and was fined $3,400 with all but $600 suspended for two years.
