GILLETTE — Prosecutors won't be able to use a Gillette man's two previous DUI convictions against him in a trial over the death of a tow truck operator.
A district court judge Wednesday ruled that the two previous cases are not admissible in Justin Helsper's upcoming vehicular homicide trial.
The Gillette News Record reported that investigators say he was nearly four times over the legal limit for driving when he struck and killed 65-year-old tow truck driver Larry Schofield along Interstate 90 in November.
County Attorney Jeani Stone declined to comment on how the decision will affect the case against Helsper.
Also Wednesday, the 28-year-old changed his plea from a drunken-driving charge to no contest. He'll be sentenced for that charge in circuit court in July.
