"Those babies (saw) every single thing that happened. That's what really makes me angry," the victim's father Santiago Jasso said.
The Jasso family lives just yards from the cul-de-sac where the party was held.
"I'm not going to bring my baby back, but at least I can find the people that did this to my son," Santiago Jasso said.
Montgomery County investigators said up to 100 people were at the party when some uninvited men started a fight. As those men left, witnesses said they hit two men. The condition of the second man is unknown.
"My son is gone. I really want to happen is justice to be done," Jasso said.
Ray Jasso's daughters are just 8 and 10 years old. Witnesses said they were setting off fire works with their dad when he was hit.
Investigators are looking for a tan or cream colored SUV that reportedly hit Jasso.
Jasso's family said this is the first weekend Ray had visitation with his daughters in about a year.
