Help Us Find Erin

My sister Erin Schmidt Vandewiele hasn’t been seen or heard from since July 23, 2018. Erin messaged friends and she said she feared for her life. She even told one friend that she would call him back the next day if she was still alive. Erin never called back. She was last seen by Joseph Mayor her travel companion to Colorado. Joseph is known to have abused Erin in the past. Joseph was arrested in Colorado and extradited to Menomonie, WI. Erin’s personal belongings were found in a hotel in Denver but no sign of Erin. Also her Id and SS card were found on a bus in Denver. I’m trying to raise money to go to Denver to search for Erin and get in better contact with the detective on the case. Please help me and the rest of Erin’s family and friends find her. Thank you all very much and god bless
