The jury sentenced Julio Blanco-Garcia, 27, to 49 years in prison, according to The Washington Post. Formal sentencing will be Nov. 15.
The college student had agreed to give Blanco-Garcia and his baby daughter a ride at a Falls Church shopping center in June 2010.
Soon after, police found Pham's body when responding to a car crash, but recognized quickly that her injuries were not due to the wreck. Pham was stabbed multiple times in the neck, chest and leg, according to autopsy reports.
The defense had acknowledged Blanco-Garcia killed Pham, but argued it was a drug-induced panic that led to the attack.
