This is from a good friend of Doris Hakman, Emmy Lou Armstrong:

Doris’s daughter, just called to tell me her mother passed away on
Sunday, July 13 at 4:30 a.m.  Jeanine was with her, holding her hand. 
Arrangements are pending.  Everyone will miss a fun gal on the tennis circuit. 
She really, truly enjoyed all the emails and was quite touched by your
concerns.  Thank you.  Emmy Lou
