DENVER -- The prosecution and the defense each had 90 minutes to deliver their closing statements Wednesday afternoon in the murder trial of Robert Ray before his fate was placed in the hands of the jury.

A year and a half after the July 4, 2004, killing of Gregory Vann, Ray's trial in the shooting death of Vann and the shooting of three others came to a close.

Prosecutors said Ray showed up to a party at Lowry Park on July 4, 2004, with a 9mm gun. They said Ray not only intended to cause trouble at the party, but intended to kill.

Defense attorneys said the shooting was in self-defense and in the defense of others.

For the parents of Javad Marshall-Fields and Vivian Wolfe, this trial is only the beginning. Ray is also accused of shooting and killing Marshall-Fields and Wolfe a week before Javad was set to testify against Ray in the shooting of Vann.

"Knowing that this was the motivation behind his murder, it's really important to me that (Ray) is found guilty of all the charges he is facing," said Javad's mother Rhonda Fields.

"This is a very important step for us," said Vivian's mother Christine Wolfe. "Robert Ray needs to stay in jail for a long time."

"It's been very frustrating to sit through this whole situation and just listen," said Fields. "The prosecution put together such a strong case."

Marshall-Fields and his fiancée, Vivian, were gunned down on July 20, 2005, at an Aurora intersection.

"This trial was about what Javad was going to testify for," said Fields. "He was not able to do that, so I'm here to be his face and his presence in the courtroom."

Although Ray is charged for first-degree murder in the death of Gregory Vann, he is not accused of actually firing the shot that killed Vann. He is charged with complicity, which means someone else committed the crime but the defendant knew that the person intended to commit a crime and they either aided, embedded or encouraged that person.
