Chief Shields said one of the suspects led investigators to the location of the body but it was not immediately clear who it was or where in the park Ms. Crawford was found.

While a motive was not yet clear, the police did take a report from Ms. Crawford on Oct. 27, just days before she was reported missing.

“In this report, Alexis described unwanted kissing and touching from Barron Brantley,” Chief Shields said.

The report also named Ms. Jones as a witness.

Ms. Crawford was taken to a hospital for a rape kit to be administered, and a clothing item and bedding were recovered from the scene, the report said.

Late on Nov. 1, Ms. Crawford was reported missing by her mother and two sisters, who all said they last communicated with her on Oct. 30.

While being interviewed by investigators, Ms. Jones had said she was not on speaking terms with Ms. Crawford because of a separate unspecified incident, the report said.

Ms. Jones told investigators that she had taken Ms. Crawford to a store where Ms. Crawford bought a bottle of alcohol and later returned home. They l ast saw each other at approximately 12:30 a.m. before Ms. Jones went to her bedroom for the night, the report said.
