On August 24th, 2018, Trinity Harvey's sister reported her missing to the Greenwood Police Department being unable to make contact with her for some time. She had initially become alarmed after receiving Harvey's phone bill in the mail and noticing that Harvey had not paid her bill in two months. Harvey's phone was under her sister's name and she was always very punctual about paying the bill. After checking Harvey's social media accounts, her sister saw that she had not been active on Facebook since July 18th. Harvey was frequently on Facebook and posting regularly, almost daily up until that point.

Harvey was originally from Minnesota. Her family later moved to Greenwood, Mississippi, where she lived for a while. In March of 2018, Harvey moved to Water Valley, Mississippi. Harvey's twin sons were living with her sister at the time and Harvey had a daughter that was living with her in Water Valley. The last time Harvey's family physically saw her was in April before she left to stay in Minnesota because she was having trouble at home. The last text Harvey sent her sister was on May 30th. Her sister also later learned that she had not paid rent in some time either.

On September 17th, 2018, the Greenwood police department handed the case over to the Yalobusha County Sheriff's Department since that is where Harvey lived and where she was last known to be. They began working on the case and were able to learn that Harvey last used her EBT card in April of 2018. They also learned she missed an important appointment in June of 2018.

The woman who is the godmother of Harvey's daughter states that she last physically saw Harvey in April of 2018 when she visited greenwood. The two would often facetime. Harvey attempted to facetime her on June 9th, but she was unable to answer. This is the last time Harvey attempted contact with her. It is unclear exactly when Harvey disappeared; however, she likely went missing sometime in June or July based on the last contact, missed appointments, and late bills.
