Prince George's County police identified the suspect from the police-involved shootout Saturday as the father of the 3-year-old that was killed.
The confrontation began when they responded to a shooting in the 4200 block of Farmer Place in Washington, Md. When they got there, they found two adults shot.
After finding the adults, the officers located the suspect in the area driving a Nissan Altima and began following him.
Frederick Roy Miller, 38, of the 8000 block of Allandale Drive in Landover, Md.. fled from police when he lost a wheel from his car around Beech Drive and Branch Avenue. Miller then exited his car and began shooting at the officers before getting back in the Altima and fleeing again. Miller stopped a second time shortly after in the 4600 block of Branch Avenue, engaged in fire once more, and eventually was shot dead by police.
After the shootout, police approached the vehicle and found a 3-year-old in the backseat suffering from "trauma to the upper body." According to police, the girl, believed to be the Miller's daughter, appeared to have been stabbed and shot by her father.
The above exclusive video was sent by ABC2 photographer Pete O'Neal's son, Patrick O'Neal, who was on Branch Avenue at the time of the second shootout. O'Neal was on his way home from work when he witnessed the suspect put his car in reverse on the other side of the road, exit his vehicle and start shooting at police. After escaping the scene, O'Neal stopped his vehicle to check for gunshots to his body or car.
"There were about five cops shooting everywhere," O'Neal said of what he witnessed. "The Altima's windows were just getting blown out."
The two adult victims, believed to be the maternal grandfather and great grandmother of the 3-year-old, were in critical condition when last reported. They were the caretakers of the 3-year-old girl. Police say the mother of the child was not home when the shooting happened, and was found safe.
The six officers involved in the shootout had a cumulative 42 years of experience between them. None were injured.
Investigators are working to determine the motive in this "domestic tragedy." Anyone with information is asked to call Prince George's County Police Department's Special Investigative Response Team at 301-856-2660.
