While the general context of multiple suspects is present, the specific detail that 'Three of the four sped off in the stolen vehicle, while the last man in the group fled in a Black Nissan' is only explicitly detailed in the context of the web search results, and no other independent source corroborates the specific split of escape vehicles.

The detail that 'Both women suffered minor injuries but declined medical attention at the scene' is reported across multiple web search results, but the evidence provided does not contain enough distinct, independent sources (like multiple news outlets reporting this specific detail) to elevate the verdict beyond single_source, though the consensus is strong.
