Federal prosecutors had recommended nearly 20 years for Harshkumar Ramanlal Patel, and nearly 11 years for the driver who was supposed to pick them up, Steve Anthony Shand, who got 6 1/2 years Wednesday with two years’ supervised release.

“The crime in many respects is extraordinary because it did result in the unimaginable death of four individuals, including two children,” U.S. District Judge John Tunheim said. “These were deaths that were clearly avoidable.”

Patel’s attorney, Thomas Leinenweber, told the court before sentencing that Patel maintains his innocence and argued he was no more than a “low man on the totem pole.” He asked for time served, 18 months.
