About a year and a half ago I had a falling out with a longtime friend. A lot of it was fueled by two other people, but the bottom line is we haven't talked in a very long time. I saw a post on FB that made me believe her father had passed away. I sent a message to a mutual acquaintance (whom she also doesn't talk to anymore but works in the same place) to ask about it. In the interim, I googled the last name and the city to see if there was an obit and there was a story about a shooting of a man done by his son. I wasn't sure of the father's first name, but I was pretty sure the son's name was her brother. The mutual friend got back to me and sent me a link to another news version of the same story, confirming everything. Even though we're not in contact, I feel like I should send a sympathy card. Just saying something like, "I'm sorry for your loss. Thoughts and prayers are with you and your family." Do you think this is acceptable? Not going in to detail about what I know and who told me,but just a very general comment that I'm still thinking about her? Or is it overstepping since we're not really friendly anymore? I just can't imagine the pain her family is going through.
