BOISE -- A woman arrested in connection to the shooting of a 30-year-old Meridian man will face additional charges, prosecutors say.

Elena Pena, 27, was arrested Friday along with her boyfriend, 34-year-old Lyle Corson. Another suspected shooter has neither been charged or publicly identified, and Garden City Police have declined to say whether that man is in custody or still at large.

The Ada Coroner said Tuesday afternoon that the victim - Paul Wyatt Russell Jr. - died of a single gunshot wound to the head.

Prosecutors say the shooting that killed Russell happened after Pena quarreled with the victim's friend near the intersection of West 39th and Stockton streets Thursday evening.

Prosecutor Shelley Akamatsu said Pena was heard telling the victim's friend that she was going to "call her boys, and they're going to come deal with him," she said.

Russell was not involved in the argument, but showed up at the intersection after his friend asked him for a ride. Other people in Russell's car told police that when they arrived, they noticed a boxy gray car parked facing away from them.

Akamatsu said the victim's friend asked Russell and his passengers whether they had a gun. Moments later, two men in the gray vehicle stepped out of the car and opened fire, prosecutors say.

Russell was struck "and stopped breathing, essentially, where he was standing," Akamatsu said.

"Elena Pena then is heard to be laughing and saying 'I told you so,' and then she gets in this gray, boxy car with the two shooters and they flee the scene," she said.

Russell was rushed to the hospital in critical condition, Akamatsu said.

Witnesses to the shooting identified one of the men who shot at Russell as Corson. Officers tracked him and Pena to a gas station near Curtis Road and Fairview Avenue Friday afternoon.

The car was packed with what appeared to be all Pena and Corson's belongings, Akamatsu said. Pena was taken into custody on a felony charge of aiding and abetting aggravated battery, while Corson was arrested on a warrant for violating his felony probation. He has not yet been charged in connection to the shooting.

Police say Corson had $700 and 10 grams of meth on him when he was arrested, while Pena had a scale and 2.2 grams of meth.

Pena originally denied involvement in the shooting during interviews with detectives, then said she had not intended for Russell to get shot, according to Akamatsu.

"She says to them, 'that's not how it was supposed to happen, I was just trying to get a ride out of there,'" Akamatsu said.

The judge set Pena's bond at $500,000. She is due back in court Nov. 7.
