An investigation into how a man charged in the deaths of seven motorcyclists in New Hampshire kept his license despite facing drunken driving charges found that Massachusetts motor vehicle department workers weren't properly processing out-of-state notifications about driving offenses.
The interim report released Monday by the Massachusetts Department of Transportation sparked by the New Hampshire deaths found the notifications were being sorted into bins and stored.
The report found the practice began in March, 2018.
A review of the records in the past five days resulted in license suspensions against more than 500 Massachusetts drivers.
The report found Connecticut twice alerted Massachusetts about a drunken driving arrest against 23-year-old Volodymyr Zhukovskyy.
Despite the alerts, Massachusetts failed to suspend Zhukovskyy's license. He pleaded not guilty to seven counts of negligent homicide.
