One person involved in possibly the largest fentanyl bust in state’s history has been sentenced to federal prison. According to court documents, Edwin Salinas was found guilty of conspiracy to deal fentanyl Monday. He has been sentenced to life in prison. The charges stem from an incident in Roberts county last November, when authorities stopped Salinas and Berta Gonzalez at a Roberts county rest stop. Upon further investigation police claim they found more than three pounds of powder and more than 53,000 pills all containing fentanyl. Police allege the two were part of a drug smuggling conspiracy between California and Minnesota.
