Lane, originally from Melbourne, was a student at East Central University in the town of Ada and was shot in the back while he was jogging on a street in Duncan, Oklahoma, on August 16, 2013.

The jury only took a little over an hour to find 17-year-old Luna guilty of first-degree murder, after a four-day trial.

• The Chris Lane emergency call
• NFL star guilty of murder
• Murder charge for US cop

“He’s gone for life,” Lane’s father Peter said.

“He’s now 17 and will not see the free light of day in the free world ever.”

Luna did not show remorse or provide an explanation for his actions before he was sentenced.

The district-attorney said Luna also expressed no emotion at the verdict, nor sentence. During the trial, prosecutors said Luna, along with Michael Jones and James Edwards Junior, decided to kill someone “for the fun of it”.

Luna’s lawyers admitted he fired the shot but said that it was not intended to kill.

They had sought a charge lesser than first-degree murder.

In Oklahoma, the prosecution does not have to prove pre-meditation in terms of targeting or planning, as the law says “intent can be formed in an instant”.

Last month Jones entered a guilty plea to second-degree murder.

Jones was the driver of the car from which the bullet was fired.

He will not be able to apply for parole until he is 56.

Lane was on a baseball scholarship at the university and was two weeks away from celebrating his 23rd birthday.

Earlier this week, Lane’s parents Peter and Donna sat surrounded by the family of his then girlfriend Sarah Harper as they heard several hours of gut-wrenching testimony.
Local resident Joy Smith recalled how she tried to save Lane’s life but could not find a pulse.

Richard Rhodes, who had been painting a house at the time, said he heard a pop that sounded like a gunshot then a black car came around the corner and sped off.

Outside the courtroom he spoke of his motivation for coming forward.

“I just wanted to come and make justice for that young man. That’s all I’ve got to say,” Mr Rhodes said.
