Please note that there are 1000s of John Karr's and John Carr's in the US.
His name is John Mark Karr, according to the latest reports, and is 41 or 42, depending on which report you read. You might try to check a people database first and if you find that the John Karr in question has a different middle name or initial, or is much older or much younger, then just post a general blurb, with a disclaimer on the name.
Thanks.
your right.
