Gerald Michael Anthony Gurule, and two other men, went to the Grizzly Rose, a popular country western dance club, in December 2008 where they planned to break into cars in the parking lot.
They were confronted by a security guard and an off-duty police officer who went to investigate after seeing three men with bandanas in the parking lot.
During the confrontation, Gurule opened fire and killed Minnick.
Gurule was indicted in 2013 and plead guilty to reckless manslaughter and two counts of attempted first-degree assault. He received the maximum sentence under the plea agreement, said court spokeswoman Sue Lindsay.
“This was a very difficult cold case,” said District Attorney Dave Young in a statement. “Under the circumstances, I am very satisfied with the sentence. I want to thank the Adams County Sheriff’s Office and our prosecutors for their work in bringing Mr. Gurule to justice.”
Jennifer Lewis and Stanley Gurule were also indicted in the murder case.
Prosecutors said Lewis drove the getaway vehicle. She was convicted of first-degree murder and given a life sentence in prison.
Stanely Gurule was charged with being an accessory to a crime but the case against him was dismissed in 2013.
