Yet extended delays in crash investigations over the past five years are strikingly routine, a Globe review of State Police records has found.
State troopers assigned to the reconstruction unit took an average of about 10 months to complete each of more than 1,900 investigations initiated from January 2014 to Jan. 23, 2019, records show. An additional 321 investigations — most involving fatalities — remain incomplete, with more than a third open for more than a year. More than 40 of those cases have been pending for more than two years.
By contrast, reconstruction units in a number of other states — Rhode Island, Vermont, Maine, Virginia, and Michigan — reported a much quicker pace to resolve cases, ranging from an average of one to three months.
