A convicted killer has pleaded guilty to a second deadly attack - this one at a motel in Langley’s Walnut Grove neighbourhood. Justin Bos has entered the plea for a lesser manslaughter charge in the killing of Cody Mostat in March of 2022. Mostat could not be revived after being found outside the Highway Hotel on 88 Avenue. In November, Bos was convicted of manslaughter in the shooting death of a man in Surrey in that same year. Bos also has a criminal record that includes drug, firearms and stolen property convictions.
