Sebestian Olivares-Coster

Sebestian Olivares-Coster listens to sentencing testimony on April 2, 2010, in Judge Dorothy McCarter's courtroom.

A Helena man who killed one teenager and seriously injured two others in a 2009 shooting on Rodney Ridge was denied parole again earlier this week.

Sebastian Olivares-Coster lured the three teenagers to the Rodney Ridge area to fight and then ambushed them with a handgun, shooting at them 15 times and pistol whipping the victims. Cory Andrewski died from his wounds while the others dealt with both physical and mental trauma from the attack.

Olivares-Coster pleaded guilty to one count of deliberate homicide and two counts of attempted deliberate homicide. He was sentenced to three life sentences by Judge Dorothy McCarter in 2010, with two of those sentences to run consecutively. McCarter believed the sentence would not allow Olivares-Coster to be eligible for probation or parole for 60 years, but because he was still just 17 years old at the time of the crime, the restrictions on parole were rescinded.

His first parole hearing was in 2013, just four years after the shooting. At the time, the Independent Record reported that the Montana Board of Pardons denied his parole with very little discussion. 

At Tuesday's parole hearing, Olivares-Coster spoke about his motivations for the crime, how he spends his time in Montana State Prison and his desire to prepare himself for re-entering the workforce.

Lewis and Clark County Attorney Leo Gallagher said Olivares-Coster's actions were "purely and simply an act of evil."

Gallagher went through Olivares-Coster's family and medical history, referencing the Montana State Hospital's opinion that previously diagnosed personality disorders make it difficult to treat him because he knows what to do and say to accomplish his objectives. 

Olivares-Coster was even compared to Nathan Leopold and Richard Loeb, two young killers who conspired to commit the "perfect crime" when they murdered a boy in the 1920s in Chicago. 

Joey Wohlers and the parents of Kahner Leary spoke about the effect Olivares-Coster had on their lives. Wohlers and Leary were both injured in the shooting. 

Wohlers, now a pre-med student at Carroll College, said he forgave Olivares-Coster but believes he should stay in prison because he could kill again.

Leary's parents said their son had suffered massively from the shooting. Leary suffers from mental health issues and struggles daily with the impact of Olivares-Coster's attempt to kill him.

At the end of the hearing, Olivares-Coster apologized. 

"I'm sorry. It wasn't a game. I'm sorry you have to go through this every six years, I'm sorry," he said.

The Probation and Parole Board will reconsider his case in 2025.
