A Cleveland courtroom was cleared after a brawl almost broke out when the victims' enraged family member tried to attack the man responsible for their deaths.
James Henderson entered guilty pleas Wednesday to the November 2014 killing of his best friend Ja'Rio Taylor, 18, Lemon Bryant, 60, Shaylona Williams, 17, and Ja'Rio's mother, 41-year-old Sherita Johnson, who was pregnant at the time.
He also shot at a nine-year-old girl as she was entering her home, but the bullet only grazed her.
Distraught family members packed the pews of Cuyahoga County Common Pleas Court on Wednesday to see the killer be sentenced. Delray Sanders, the brother of Sherita Johnson, was first to give a victim-impact statement.
"You are so pitiful as a person," he said.
"Now I'm the oldest child in my family. I'm going to do everything in my willpower to make sure everybody in my family has everything and then some."
Later on Mr Sanders caught Henderson smirking and addressed the hearltess gesture verbally, but eventually became so incensed he made a run at him.
"I'm really glad that you're suffering. Right now you've got that smirk on your face, but when you're sitting in that cell and living out of one of them rooms, it'll get real serious, 'cause you ain't been there yet," he said.
"I'm just thankful that God made a way for us to find out who you are," he continued, before suddenly trailing off and sprinting at Henderson, who was protected by police officers.
Mr Sanders' attempts to get to Henderson were immediately contained and the courtroom was cleared. Some of the victim's friends and family were asked to leave the courthouse after the incident and more officers were brought in.
Henderson was arrested at a McDonald's in Lakewood, nearly six months after the deadly shooting. He still had the murder weapon in his belt.
