A St. Louis jury has convicted a 20-year-old man of murder in the death of a Vietnamese immigrant in a "knockout game" attack.
Elex Murphy was convicted Wednesday of second-degree murder, first-degree assault and armed criminal action, in the April 2011 death of 72-year-old Hoang Nguyen. Murphy could face up to life in prison with the possibility of parole. His trial began Tuesday.
The jury rejected the prosecution's request for a first-degree murder verdict, The St. Louis Post-Dispatch reported.
Nguyen was walking home with his wife when he was attacked by a four teenagers. Three other people were reported to be with Murphy that day, but no one else was charged in the case.
In the knockout game, people are picked at random and beaten. The attacks are sometimes captured on cellphone video, and some have been posted on social media sites.
The defense argued that no physical evidence linked Murphy to the crime, and that the DNA of another man was found in blood on glasses that had been knocked off the victim's wife, Yen Nguyen, during the attack.
Yen Nguyen, 62, had identified Murphy in police photos and a lineup as their attacker.
Later, through the interpreter, Yen Nguyen told a reporter, "I feel that truth, that justice, has arrived. I thank God."
