The Jam Master Jay for Youth Foundation is organizing a benefit concert for the slain DJ to commemorate what would be his 39th birthday.Marvin Thompson, who is heading the charitable foundation, told the Queens Village Times-Ledger that the proposed concert would take place on January 21.In addition to the concert, the organization will hold a scholarship luncheon next month. Thompson said almost 1,000 students will receive $2,000 in scholarships and a laptop computer.”It’s a really positive thing we are trying to do,” Thompson said. “We’re hoping to get support from the community and corporate sponsors so we can continue the scholarships.”Police have yet to charge anyone with the legendary DJ’s killer and are probing several motives for his shooting death.
