A 27-year-old man was convicted today of murder for the slayings of his then-girlfriend's grandparents in 2010, the Los Angeles County District Attorney's Office announced.

Deputy District Attorney Scott McPheron of the Family Violence Division said jurors deliberated for two days before finding Roldolfo Lopez guilty of two counts of first-degree murder. Jurors also found true a special circumstance allegation of multiple murders.

Lopez is scheduled to be sentenced on Jan. 24, 2017 and faces a possible maximum sentence of life in prison without the possibility of parole. Lopez and Sophia Cristo, now 20, fatally stabbed her grandparents, 71-year-old Jack Bezner, and his wife Susan, 64, on Aug. 9, 2010. Lopez and Cristo, who was 14 years old at the time of the murders, then fled to Texas.

In March 2015, Cristo was found guilty of first-degree murder. Special circumstance allegations of lying in wait and multiple murders were found to be true. Jurors also found true that Cristo personally used a knife to stab Susan Bezner.

Cristo faces life in prison when she is sentenced next month. She was ineligible for the death penalty because of her age at the time of the murders.

Case BA361170 was investigated by the Los Angeles County Sheriff's Department.
