In the last 10 years, the only way Sue and Willie Coleman kept up with their estranged son's life was through headlines: his marriage, his legal problems, and finally, his hospitalization and removal from life support on Friday.
"We would've loved to have been there by his side at the hospital, to let him know we love him before he passed away," Sue Coleman, 67, tells PEOPLE. "This is a shock to us. We loved Gary very much. We're going to miss him."
