FLAGSTAFF, AZ (3TV/CBS 5) -

More information has been released concerning the Northern Arizona University shooting that happened on Oct. 9.

Toxicology reports are back, and they show that all of the victims who were shot that night had been drinking, but the suspected shooter, Steven Jones, was completely sober.

It's a new detail criminal defense attorney Russ Richelsoph said could work in Jones' favor.

“Alcohol and drugs or guns just don't mix. Juries don't like it,” Richelsoph said. "It definitely hurts the prosecution in this case.”

According to the Northern Arizona University police investigation report, the victims were impaired.

“Alcohol affects a couple of things,” Richelsoph said. “One, it affects their behavior, but it also affects their ability to perceive, so their testimony in court when these three men testify about what happened and what they saw Steven do, their statements aren't going to be as believable because they were under the influence of alcohol versus Steven, who doesn't have any alcohol influencing him.”

Jones is accused of shooting four men on NAU’s campus, killing one of them.

Jones reportedly told police that before the shooting there was a fight, he was hit in the face, he went to his car while being chased, and that's when he reached in to get his gun.

"I don't think there's any doubt at this point he was attacked by individuals outside that parking lot and then chased into that parking lot. That's really clear from the police report," said Jones’ attorney, Burges McCowan.

The next hearing in this case is scheduled for Jan. 21.
