Colorado cinema gunman, James Holmes, has been found guilty of the first-degree murder of all 12 victims and will be eligible for the death penalty, according to a Sky news report.
Jurors rejected his insanity defence and found him guilty of killing them with “extreme indifference”.
He was also found guilty on dozens of counts of attempted first-degree murder.
The jurors took about 13 hours to reach their decision following nearly three months of often emotional testimony.
They will return to court on Wednesday to hear from more witnesses to decide whether Holmes will be executed or jailed for life without parole.
His lawyers are expected to argue his life should be spared because of what they say is his severe mental illness.
The verdict brings an end to what has been a three-year wait for the victims and their families.
