Monday is the fifth anniversary of the disappearance of Lisa Stebic, whose family says they know the Plainfield woman is dead.

She was reported her missing on April 30, 2007. Her estranged husband, Craig, told police his 37-year-old wife left the house they were still sharing to go for a workout and never returned.

Family members told WBBM-TV (Channel 2) that their frustration now is not having closure on Stebic's death because her body's never been found.

“Lisa’ still missing,” her cousin, Melanie Greenberg, told the television station. “We know she’s dead, but we don’t have a body. We don’t have a place to mourn.”

Lisa Stebic's sister, Debbie Ruttenberg, left this note on the family's Web site, www.findlisastebic.net:

"Five years. Lisa’s body hasn’t been found…yet. We haven’t received due justice…yet. We haven’t even been able to hold a funeral! 

It never gets any better - it’s actually worse than any movie or program. Every moment Lisa is missed. Sleep brings nightmares and daily life remains empty. Possibly the worse addition is that Lisa’s children aren’t able to be in our lives and we aren’t able to be in theirs. How does one totally remove a mother and her family from his own children? 

"To attempt a life that is worthy, I can only hold Lisa’s memory in the most beautiful light. A light that shines glorious colors and has a unique brightness throughout everyone she touched in her shortened life. This comes from her pure joy and positive energy that radiates within us. Especially within Lisa’s children, Lexi and Zac.

"Our family will always be devastated by our loss, but we remain hopeful for justice.”

The case was profiled on "Nancy Grace: America's Missing" in March 2011, but produced no new leads in the case.
