I think it's obvious there were at least two individuals involved.
The first burglary commenced at about 5:30, then:
At approximately 6:00 there was a camera from west of the burglarized home that captured a dark colored SUV driving quickly down the street.
Approximately one minute later that vehicle was then seen leaving.
(Vehicle leaves the area with the stolen items. It is not seen returning to the neighborhood. )
There were TV's and laptops that were taken that were sizable, that would lead us to believe they were likely loaded into a vehicle to be removed from the area.
(At some point between 6:11and 6:45, the suspect is in the neighborhood, and approaches the Blackburn home.)
Approximately 6:45-6:55, there was a neighbor who reported hearing shots, or what she believed to be shots.
(After 6:45, suspect is seen "traveling", no vehicle mentioned. I think it means walking. So who drove away in the vehicle?)
Another neighbor saw an individual wearing a dark colored hoodie traveling from the first burglarized home.
(This time -- after the murder -- he's definitely walking. He's not driving the dark SUV because it's been driven away by a second individual right after the first burglary. It did not return since there was no loot to haul off. The killer likely alerted the driver of the shooting, and had the driver pick him up outside of the immediate area, rather than driving in again and attacting attention. JMO)
Later on...occupants from that same residence reported seeing a subject wearing a hoodie walking westbound, away from the area of the Blackburn residence.
This individual was captured on a surveillance camera both on that street and on the neighboring street.
Further neighbors on the neighboring street did see that individual with the same hoodie cinched down attempting to cover his face.

Bottom line, you have a vehicle which drives out of the neighborhood and doesn't return. Yet afterward, a suspect is still walking around the neighborhood.
one driver + one walker = two perps.

As for visibility, burglars have emptied roomsful of furniture from homes and no one paid attention.
