Human remains found last week in a wooded area of north Alabama have been identified as those of Makenna Joy Purvis, the DeKalb County teenager reported missing in September, authorities said Monday.

The remains were found in a thick, wooded area of Valley Head by the Huntsville Search Dog Unit, DeKalb County Sheriff Nick Welden said shortly after they were discovered March 23.

On Monday, the sheriff announced the remains were identified as those of Purvis, 19, of Valley Head.

Foul play is not suspected, Welden said.

“This is such a terrible tragedy, and I cannot even begin to imagine the pain that this family is feeling at this time,” the sheriff said in a statement. “Thank you to all that volunteered time to help search for this precious girl, we had all hoped and prayed for a different outcome.  Please keep the family and friends of Makenna in your prayers for months to come.”

Welden said Purvis’ family requested privacy. A memorial for her would be planned “at a later time.”
