The trial for a truck driver charged with causing the deaths of seven motorcyclists in northern New Hampshire in 2019 is now expected to start in July — more than three years after the crash — to give the defense more time to find and work with a crash reconstruction expert. Volodymyr Zhukovskyy, 25, of West Springfield, Massachusetts, was days away from jury selection in November when his lawyers filed a motion saying they could no longer present their accident reconstruction expert at trial. “We’ve experienced significant difficulty in identifying an expert that’s qualified, has appropriate resources and is willing to accept the case,” defense lawyer Jay Duguay told Coos County Superior Court Judge Peter Bornstein during a status conference on the case Tuesday. Lawyers and Bornstein also talked about scheduling conflicts. Another status conference was planned for January. Zhukovskyy pleaded not guilty to multiple counts of negligent homicide, manslaughter, driving under the influence and reckless conduct stemming from the crash that happened in Randolph on June 21, 2019. He has been in jail since the crash.
