The Crown is asking for a dangerous offender designation for a B.C. man who plied two teenaged girls with booze and drugs and was eventually convicted of killing them.

Martin Tremblay was convicted of criminal negligence causing the deaths of 17-year-old Martha Jackson and 16-year-old Kayla Lalonde, who died in March 2010 after partying at Tremblay's home.

Crown lawyer Michaela Donnelly says Tremblay has demonstrated a pattern of grooming vulnerable young girls, who are almost always aboriginal, and providing them with alcohol and drugs.

She says Tremblay has an extensive criminal record, including convictions for sexual assaults that occurred in 2001.

Donnelly says Tremblay is aggressive towards young girls and concerned about the risk his behaviour poses to them.

She says Tremblay has demonstrated that his chances to be treated are low and that he would pose a danger to the public if released.
