Qundan (Jenny) Chen left Seattle, WA on March 1, 2016 for a backpacking trip through Mexico. She was in the middle of a solo trip that started from San Diego into Mexico, heading to Cancun before a trip to Cuba. Her family last heard from her when she was in Oaxaca, Mexico and was planning to meet her husband in Cancun on April 15th, but never showed up. Chen's husband hired a private investigator in Mexico who tracked her route on April 11th from Oaxaca City to Juchitan, approximately 6 hours away. On April 12th, Chen was trying to catch a ride from Juchitan toward Cancun and at about 2pm, eyewitnesses saw the driver of a Corona beer truck offer her a ride. Chen left with the driver and has not been seen since.
