"He got what he deserved, he did. It doesn't bring back my son," said the victim's mother, Michelle Ramirez.
"I mean I'm glad this part's over, but we're never going to get over anything with what happened to Anthony," said Theresa Thompson, the victim's aunt.
Young Anthony Ramirez was gunned down in a San Bernardino park while playing basketball with his brothers and friends back in 2006.
The shooter, Bagsby, was only 15 at the time but was believed to be a gang member.
Family members said it was hard to contain their anger in court Monday morning as Bagsby sat there.
"I wanted to jump over and kill him, straight up," said the victim's brother, Larry Ramirez, who was also hit by gunfire that day.
"I miss my brother a lot. I have a lot of anger, a lot of aggression, just trying to deal with it," he said.
The reading of the verdict comes on the first day of National Crime Victims Rights Week. What does that mean for this family? They're pushing to make sure anyone who commits a crime like this is charged as an adult.
"And my feelings on this, no matter what age you are, if you commit a murder like that, you should be tried as an adult, and hopefully one day we will work on a thing called Anthony's Law to get that going," said Stella Sanchez, a supporter of the Ramirez family.
Because he was a juvenile at the time of the crime, Bagsby was not eligible for the death penalty.
Bagsby faces 40 years to life in prison when he is sentenced June 8.
