I remember a home they lived in and it was in Santee, not Lakeside. Tammy was a Sophmore or Junior at Santana High School while I was a senior in 1988 the saddest news to hear before we graduated was that Tammy lost her sister. I roller skated and the little dance studio next door was where little Tammy and Heather started their fame. 
Sleep with Angels little Heather we miss you still so so much.
