BAKERSFIELD, Calif. -- One of the teenagers accused of killing an elderly couple in a southwest Bakersfield home has been found guilty on murder charges.

The jury of seven women and five men found 18-year old Luis Palafox guilty on two counts of first-degree murder in the stabbing and beating death of Joe and Dorothy Parrott.

The case was handed over to the jury Monday afternoon, and after seven hours of deliberating, the jury came to a decision around 3 p.m. on Tuesday.

Palafox and his 18-year-old uncle Kyle Hoffman are accused of breaking into the Parrott's home and stabbing and beating them to death two years ago.

Hoffman has told detectives it was Palafox who killed the couple while he stayed behind. But during the trial, the defense has argued there was no proof that placed Palafox at the scene.

The jury did not agree and found Palafox guilty on two charges of first-degree murder.

Palafox now faces 25 years to life in prison, which is a sentence his attorney, Michael Lukehart said could pose some issues.

"There will be some interesting constitutional issues in adjudicating the sentencing because it is still a little bit of an open question as to whether you can sentence a juvenile to life without parole," Lukehart said.

Palafox was only 16 at the time of the killing.

But was tried as an adult.

Hoffman, who is being tried separately is also being tried as an adult.

Closing arguments in Hoffman's case ended Tuesday afternoon and then was handed over to the jury to begin deliberations.

Palafox will be back in court for his sentencing next month.
