DENVER (KDVR) — On June 20, 2005, Javad Marshall-Fields and his fiancée, Vivian Wolfe, were shot and killed while driving on Dayton Street in Aurora.

Marshall-Fields was the son of Colorado State Sen. Rhonda Fields, and on Wednesday, the Colorado Supreme Court unanimously ruled that the man convicted of their murders will not get a new trial in the case.

Justice William Hood III said in the ruling that while evidentiary issues did arise during the trial of Robert Keith Ray, the issues did not impact the fairness of the proceedings or the jury's verdict.

The case spans years, and the 18th Judicial District Attorney released a timeline of events to help shed light on what happened. The DA said that in 2004, Ray got into a dispute with event organizers, Gregory Vann and Marshall-Fields. Vann was killed, and Marshall-Fields was injured.

A year later, Marshall-Fields and his fiancée were shot and killed before they could testify against the man accused of killing Vann, according to the DA's office. That man, Sir Mario Owens,

Both Vann's and Marshall-Fields' killers were convicted in their separate cases and were sentenced to death, which was commuted to life imprisonment after the state repealed its death penalty.

“The Colorado Supreme Court has made it clear: Robert Ray will remain exactly where he belongs—behind bars for the rest of his life,” District Attorney Amy Padden said. “Justice has prevailed. The victims’ families and our community can take comfort in knowing these killers will never walk free."

Postconviction proceedings were delaying the Colorado Supreme Court's ruling on Ray's appeal, the DA's office said.

“The Supreme Court’s unanimous affirmation of both Ray and Owens convictions ensures that the criminal justice system will seek out those who attack that justice system by killing witnesses,” Chief Deputy District Attorney Ann Tomsic said in the 18th Judicial District Attorney's Office release. “On behalf of the victims’ families and the community that was so stunned by these murders, we are grateful the Court recognized that the trial, despite its complexities, was fair and the verdicts were sound."

Ray argued in his appeal that his life without parole sentence was unconstitutional under the Eighth Amendment and sought an evidentiary hearing on the matter. The hearing was denied.
