"I want his life to be a living hell as mine has now become," Shennewa Dean said.
"Sorry, not sorry, from a broken mother."
Dean says Christopher Williams "broke" her after killing her son, Kylin Baca-Fulmer, in a Southwest Fresno shooting.
Action News was not allowed to show Williams's face in court, but we saw him smiling and at times winking toward his victim's family.
Baca-Fulmer's sister, Brittney, saw it, too.
"He just had no remorse," Brittney Fulmer said.
A Fresno County jury convicted Williams of murder, shooting at a car, and assault in September.
Prosecutors say he was involved in a July 2021 shooting that left Baca-Fulmer dead in the driver's seat of a car.
ShotSpotter sensors picked up on 13 shots near the corner of Calwa and Bardell Avenues.
"The crime was very, very dangerous. It did endanger public safety," Judge Gregory Fain said.
Part of the incident was recorded on a Facebook Live when prosecutors say Baca-Fulmer told viewers he was being followed.
It is unclear what motivated the shooting, but Williams's own defense attorney has previously said Williams is a gang member.
In court on Monday, Brittney Fulmer seemed to suggest there was an ongoing rivalry.
"To, you know, him, he might've been a 'top dog.' To us, that was our baby," Brittney said.
Kevin Coleman is the man who prosecutors say actually pulled the trigger.
He has pleaded not guilty to murder and is due back in court on Thursday.
