A 12-year-old boy and two teenagers are accused of beating a 70-year-old man to death during a carjacking, police in Philadelphia said.
Officers were called to a location on Teesdale Street shortly after 10:30 p.m. Dec. 2 and found the victim, Chung Yan Chin, unresponsive and bleeding from his face and head.
Authorities said Chin's Toyota Camry had been stolen.
He was taken to the hospital in critical condition and died weeks later, on Dec. 21, according to police.
John Nusslein, 18, was arrested Jan. 14, and the 12-year-old was taken into custody Feb. 3. They were both charged with murder, robbery, carjacking and other crimes, police said.
Investigators are still searching for the third suspect, a 16-year-old boy. There is a warrant for his arrest, authorities said. NBC News is not naming the two boys because they are minors.
The deadly carjacking comes amid a spike in crimes in Philadelphia. Last week, an Uber driver was shot trying to escape during a carjacking, NBC Philadelphia reported. A 60-year-old man was fatally shot during another carjacking this month, the station reported.
