FAMILY members of a mom who vanished from the same town where Sherri Papini staged an infamous kidnapping hoax are pleading for information as the hunt to find her nears the three-month mark. Nikki Cheng Saelee-McCain, 39, was reported missing by her younger sister in Redding, California , on May 21, having not been seen or heard from for four days. The mom-of-four was last sighted on May 17 visiting one of her husband's family members at a local hospital.

Nikki texted her sister Chloe Saelee that night to let her know she was leaving the hospital to drop her mother-in-law's vehicle back at her in-laws' home located near the Redding Rancheria, a Native American reservation. She said that one of her husband's friends was going to follow in a vehicle behind her to later drop Nikki off back at her home in Redding. Chloe continued to text Nikki that night and into the early hours of May 18 but did not receive a reply.
