Well-Known Gamer’s Brother Charged With Their Killing Mother, Stabbing Father With Butcher Knife

The brother of a well-known online gamer was charged Tuesday with killing their mother and seriously wounding their father in San Juan Capistrano.

Yihong Peng, 30, was charged with murder, two counts of attempted murder and single counts of assault with a deadly weapon and attempted carjacking. He also faces three sentence-enhancement allegations: personal use of a knife, use of a deadly weapon during a carjacking and inflicting great bodily injury on the victims.

Peng faces up to 44 years to life in prison if convicted of killing his 59-year-old mother, Wei Ping Shen, and wounding his father, 59-year-old Guojon.

The defendant's brother, Yilang Peng, is a "League of Legends" star known as "Doublelift" in online gaming circles.

Yilang Peng issued a statement Monday, saying he was "still processing this news and joining up with my dad and little brother to make sure they're OK."

Yihong Peng was "behaving oddly" at a gym in San Juan Capistrano last Friday morning, prompting sheriff's deputies to give the defendant a ride home, according to the Orange County District Attorney's Office.

Later in the day, the butcher-knife wielding defendant got into an argument with his mother and father and chased them out of their home before stabbing the victims multiple times, then attempted to stab another man nearby in a parked vehicle, prosecutors allege. He's also accused of attempting to carjack another bystander, who was cut several times as he resisted.
