A transient was convicted Thursday of fatally bludgeoning an 89-year-old man and his 75-year-old wife during a burglary at their multimillion-dollar home the day after Christmas in 2014.
Jurors found Luke M. Fabela, 27, guilty of first-degree murder and residential burglary stemming from the Dec. 26, 2014, slayings of Armie "Troy'' Isom and his wife, Shirley, at their home in an unincorporated area near La Verne.
The jury found true the special circumstance allegations of multiple murders and murder during the commission of a burglary, along with an allegation that a weapon was used, according to Deputy District Attorney Tannaz Mokayef.
Fabela was also convicted of an unrelated residential burglary on Jan. 14, 2015. Jurors acquitted him of a robbery charge involving Shirley Isom.
Prosecutors had opted earlier not to seek the death penalty against Fabela, who is facing life in prison without the possibility of parole.
Sentencing is set for Aug. 30 at the Pomona courthouse.
Shirley Isom was found dead in the driveway next to her car, while her husband was found inside the house and died that day of blunt force head trauma after being taken to a hospital.
A groundskeeper discovered the bodies.
The only item taken was a cellphone belonging to Shirley Isom, which was never found, according to Mokayef.
