Teenage best friends Mason Rist and Max Dixon died after a brutal attack that lasted 33 seconds - cut down by machetes in a case of mistaken identity, yards from Mason's front door.
Five people - four teenagers and a 45-year-old man - have been detained for their parts in the murders.
Riley Tolliver, 18, and 17-year-old Kodishai Wescott, who was identified on Thursday for the first time after reporting restrictions were lifted during sentencing, were told they would each be detained for a minimum of 23 years.
A 15-year-old boy and a 16-year-old boy, who cannot be named for legal reasons, were detained for life with minimum terms of 15 and 18 years respectively.
The murders have left many shattered hearts in their wake, not least Mason's older sister Chloe Rist, who left those in the courtroom stunned with her emotional impact statement while holding aloft her brother's ashes and a lock of his hair.
