Victoria Gbojueh mourned with family and friends Sunday during a vigil for Gbojueh’s sister, Beatrice Wilson, and Wilson’s grandson, Peter Wilson, outside the Minneapolis house where they were murdered last Monday.

Ishmael Roberts, Beatrice Wilson’s son, is accused of killing both with a samurai sword. 

Roberts, 22, has been charged with two counts of intentional second-degree murder. He was arrested in Waterloo, Iowa, where he rolled his mother’s car while trying to flee police.
