The only place I saw any news about this was deep down in John Horgan's column where he wrote:

A TRAGEDY IN BURLINGAME: Law enforcement authorities have been investigating why a 34-year-old San Francisco man apparently jumped (or fell) off the top of the multistory Safeway Store on Howard Avenue in Burlingame early in April. He somehow survived the approximate 30-foot plunge. But, sadly, he later died of his traumatic injuries at Stanford Medical Center. The Santa Clara County Medical Examiner’s office had not provided a definitive cause for the tragedy on its website as of noon Monday.

I park up there off and on–more "on" as the on-going refresh of the store continues–and it's hard to see how one could fall off.  Let's hope there's no criminal activity involved.
