The 13-year-old Dorval boy who pleaded guilty to shooting and killing his brother has been denied a request to be released from custody while he awaits sentencing. 

He shot his 16-year-old brother last January in their Dorval home.

The teen was in court this morning after he pleaded guilty in September to criminal negligence causing death using a firearm, armed robbery and shoplifting. 

On Friday, a judge ruled there had not been any significant changes or new evidence to justify modifying the teen's current custody arrangements. 

Family members had offered to take responsibility for him, but instead the 13 year old will return to a facility for young offenders.
