This information was sent to us from her brother Rick:

"Jackie died November 11, 2000 from brain cancer that had metastasized from lung cancer. She had one section of lung removed before that...
 
She had 2 kids from a previous marriage, both boys...Jesse now 39,  Joshua now 32. She had Jesse one year after graduation. Jackie lived all over the country and remarried Jeff Treuheit in Oct 1990 in Fort Myers Fla.

She got lung cancer in 1998 and went downhill from there... she fought it to the end."

Rest in Peace, dear friend...
