The suspended state trooper charged with drunken driving and other offenses in a deadly Plymouth wreck that killed a Carver mother and daughter a week and a half ago has yet to face a judge, but the police chief whose detectives are investigating says the delay isn’t unusual.

State Trooper Jonathan Basler, 25, of Kingston was suspended without pay indefinitely yesterday as state police conduct an internal probe to determine whether he broke department rules in the Sept. 22 crash. Meanwhile, Plymouth cops say the court case is moving just as slowly as any other incident where the defendant is cited rather than arrested on scene. They have said they did not arrest Basler at the scene or in the hospital because they initially had no reason to suspect he was drunk when they arrived at the scene of the crash that killed Susan Macchi, 64, and her daughter Juliet Macchi, 23.

“Take the trooper part out of it, and it is what it is,” Plymouth Police Chief Michael Botieri said of Basler, who was cited Friday. “So at this point, they’ll process it as a summons and summons him to court. That’s a normal process that takes a few weeks. Whatever it is, it is, and that’s the date he’ll be in court.

“When we write these citations and don’t place people under arrest, that’s the time frame it takes,” Botieri said. “I don’t think it’s slower than any normal case we do.”

Basler, also charged with carrying a firearm while under the influence of liquor and improper storage of a non-large-capacity firearm, joined the state police last year and worked out of the Milton barracks.
