The massacre happened the morning of January 16 at a property on Harvest Avenue near Road 68.
No arrests have been made in this case, but Boudreaux believes the shooters have gang ties.
He said that when arrests are made, he would like Gov. Gavin Newsom to lift the ban on the death penalty in cases where small children are murdered.
"This should be a death penalty case," Boudreaux said.

Three people survived the shooting. Two of them were inside a trailer, and the other was inside the house.
Boudreaux has described the attack as a "cartel-like" shooting that was methodical and merciless.
