Sounds like they're still looking for the same person. This was evidently the first person who came by to see the van, although they assume he was the one who returned to see it on the day the 94 year old was killed. Very sad - it says that nothing was even stolen.
May not be the guy but may provide lead. It is a (another) sad commentary on value of life. A man who served his country - disabled - beaten by scum.
