And despite all those government resources and manpower, seemingly little progress is being made in the investigation.

Weren't we told after the last shooting that the investigators were feeling more confident than ever that they would soon have the perp(s)? They had at least a partial license plate (albeit, possibly stolen) and a very good description of the driver, which hasn't been released yet to the public.

I doubt they know anything more than the rest of us do. Or if they do know they aren't telling, for the last thing they want to is tip off the perp they know his identity. The only way this will be solved is through dogged and patient police work. Either they'll catch this guy or he could just vanish like the Zodiac spree killer did back in San Franciso in the 1970s.
