4-year-old Jaeden Santiago was released from St. Christopher's Hosptial on Monday evening.
Earlier Monday, authorities promised thorough investigation into the deadly police chase.
It remains an open wound for the families of the victims.
"It's crazy," said Javier Roman.
He still can't believe that his older brother is gone. 36-year-old Danny Roman was killed when his vehicle was broadsided by another car trying to escape police Friday night.
His wife, Jenny Santiago, was at the wheel and their 4-year-old son Jaeden was in the back seat.
Jaeden's mother remains hospitalized in critical condition.
Danny's family says he was a friendly man and a hard worker, providing for his three children.
"He's a nice father, a nice person with his wife and the house. He was working for his kids and his wife," said Javier.
Danny's family wonders what would have happened if the police had broken off their pursuit.
The other driver, Gregory Alston has a long rap sheet and was recently released from prison. Police say he pointed a gun at an officer during a routine traffic stop then took off.
They will now go over all of the radio transmissions between and try to match it up with the video taken by Chopper-6.
"It's really a judgment call in many instances. The more dangerous it gets you would hope that it gets broken off," said Deputy Police Commissioner Richard Ross.
Ross says it's too early to reach any conclusions. He and other supervisors will be reviewing everything to determine if officers followed the department's pursuit policies.
Police have searched the entire route of the long chase and haven't found any trace of a gun.
"It's not uncommon that it would not have been found being that it was discarded on a city street. Someone could have picked it up, it could be under a car, it could be anywhere but we have not found it," said Deputy Commissioner Ross.
In the meantime, Alston now faces a list of charges including murder, involuntary manslaughter, and aggravated assault, among other offenses.
