Help find Lauren Pree

My wife and I have been seaparated going on 2 years in March as of September 20th, 2018 she has been missing. The last location she was seen was in Mount Vernon, IL. We have two beutiful twin girls, age 6, who have since come to stay and live with me. Everynight they ask where their mom is and tell me they miss her and cry to sleep. My goal is to raise money for a reward for someone who comes forward with where she is.
