A Port Jefferson Station man was sentenced to 4 to 8 years in prison Wednesday for crashing his car while high on marijuana, killing a motorcyclist, Suffolk County prosecutors said.

Sabelo Ndala, 22, was convicted of vehicular manslaughter, aggravated unlicensed driving and driving while ability impaired by drugs, District Attorney Thomas Spota said in a statement.

Ndala was on probation for a previous DWI conviction when the crash occurred in Coram, two days before Thanksgiving, authorities said.

He was trying to turn onto Hyson Way when his 2010 Volkswagen Jetta slammed into a motorcyclist on Old Town Road.

The motorcyclist, Thomas Heissenbuttel, 56, of South Setauket, was taken to Stony Brook University Hospital. He later died from his injuries.

His wife, Regina Heissenbuttel, in her impact statement to the court, wrote that Ndala is now “an unwanted person in my life.”

Adding the defendant has no respect for authority, she wrote that her life has become an emptiness “that is so unbearable I can’t even put it into words.”

“To kill someone is a terrible thing,” Suffolk County Court Judge Stephen Braslow told Ndala in the Riverhead courtroom, according to News 12 Long Island. “You’re going to have to live with that . . . knowing that it was preventable.”
