    Anything more on this? Her age and the hour caught me by surprise. Are there any more details?

      Yes the circumstances seem very odd. I was expecting a 90 year old in a Lincoln. 32 year old driving thru rossmore in a Subaru at 5:00am is extremely odd.

    Hard news to get for anyone at any age. Condolences to her friends and family.

    There are a lot of young caregivers in the area. Not everyone is 70+
