Eight people are now facing double murder charges over the alleged machete murders of Dau Akueng and Chol Achiek, after the boys were fatally stabbed in Melbourne's west last year.
Dau, 15, and Chol, 12, were allegedly attacked by a group of people wielding knives and machetes shortly before 8pm on September 6 in Cobblebank.
The pair were found critically injured about 200 metres apart, with Chol on Marble Drive and Dau on Cobble Street.

A 19-year-old Caroline Springs man, an 18-year-old Wollert man and a 16-year-old boy were also charged with the murder of Chol.
All eight accused have now been charged with two counts of murder.
The charged people remain in custody and will appear in court at a later date.

Dau and Chol's deaths sent a ripple of grief and concern through the tight-knit community.
A community leader in Cobblebank told 9News last year the tragedy left families feeling unsafe.
The attack took place just a week after Victoria enshrined a ban on machetes in state law.
Families of the slain children have called for stronger action.
