Justin Haevischer, 28, appeared in B.C. Supreme Court on Wednesday for the first time after being charged with accessory after the fact to the October 2007 murders.
Haevischer was wearing a baggy grey hoodie and jeans and appeared without a lawyer. He told the judge he did not understand the charge after it was read.
"I don't understand what that means. Does that mean I helped them escape or something?" he asked.
Judge Jennifer Duncan replied that was "the essence" of the charge and advised him to seek a lawyer and make a bail application. He was remanded in custody until his next court date on Jan. 7.
A Canada-wide warrant was issued Dec. 11 for Haevischer and police said he was arrested Monday at Edmonton International Airport after a passenger caused a disturbance on a plane.
He's accused of helping his brother Cody Haevischer and Matthew Johnston escape after the pair had fatally shot six men, including two innocent bystanders, in the Surrey apartment.
Cody Haevischer and Johnston were both found guilty of conspiracy and six counts of first-degree murder in October and sentenced on Dec. 12 to life in prison with no chance of parole for 25 years.
The two men were members of the notorious Red Scorpions gang.
