Deputies said Woo shot 29-year-old Jaquan Garrett in the head near Firelite Lane and Cherry Hill Drive around 10:30 p.m.
Witnesses identified Woo, who fled on foot. Garrett was transported to a hospital, but he later died.
Investigators believe an argument led to the shooting.
Woo has been charged with intent to murder and possession of a firearm during the commission of a felony. After learning that Garrett died, investigators asked for the charge to be upgraded to murder.
Woo has two prior convictions for domestic violence and one for driving while unlicensed. A reward up to $2,000 is offered for information leading to his arrest.
