Harshkumar Ramanlal Patel, 29, an Indian national who prosecutors say went by the alias “Dirty Harry,” and Steve Shand, 50, an American from Florida, were part of a sophisticated illegal operation that has brought increasing numbers of Indians into the U.S, prosecutors said.

They were each convicted on four counts related to human smuggling, including conspiracy to bring migrants into the country illegally.

“This trial exposed the unthinkable cruelty of human smuggling and of those criminal organizations that value profit and greed over humanity,” said Minnesota U.S. Attorney Andy Luger.

Federal prosecutors said 39-year-old Jagdish Patel; his wife, Vaishaliben, who was in her mid-30s; their 11-year-old daughter, Vihangi; and 3-year-old son, Dharmik, froze to death Jan. 19, 2022, while trying to cross the border into Minnesota in a scheme organized by Patel and Shand. Patel is a common Indian surname, and the victims were not related to Harshkumar Patel.

Before the jury’s conviction on Friday, the federal trial in Fergus Falls, Minnesota, saw testimony from an alleged participant in the smuggling ring, a survivor of the treacherous journey across the northern border, border patrol agents and forensic experts.

Defense attorneys were pitted against each other, with Shand’s team arguing that he was unwittingly roped into the scheme by Patel. Patel’s lawyers, The Canadian Press reported, said their client had been misidentified. They said “Dirty Hary,” the alleged nickname for Patel found in Shand’s phone, is a different person. Bank records and witness testimony from those who encountered Shand near the border don’t tie him to the crime, they added.

Prosecutors said Patel coordinated the operation while Shand was a driver. Shand was to pick up 11 Indian migrants on the Minnesota side of the Canadian border, prosecutors said. Only seven survived the foot crossing. Canadian authorities found two parents and their young children later that morning, dead from the cold.
