A Fairfax jury found Librado Cena guilty on a misdemeanor charge of assault in a road rage argument in a Best Buy parking lot last April — the other man fell ill an hour after the fight and died 10 days later. A sentencing hearing is scheduled for Wednesday morning, according to The Washington Post. The maximum sentence is 12 months in jail.

Cena, 58, allegedly hit William Hays O'Brien, 63, only once in the Best Buy parking lot in Fairfax. But O'Brien would die 10 days later, reportedly from a head injury during the fight.

O'Brien had allegedly been honking his horn at Cena before stopping at the Fairfax store. Security footage released by Fairfax City Police shows Cena approaching O'Brien from behind in the parking lot. The two have an altercation, followed by O'Brien walking into the store and Cena driving off.



Roughly an hour later, O'Brien called 911 from his home with a headache and said he "couldn't think straight." Paramedics found him unresponsive. O'Brien spent several days in the hospital, but died from what the medical examiner called "complications from blunt force trauma to the head."
