ELMWOOD, La. (AP) — DNA tests have positively identified the body of a 2-year-old that was found under a bridge near New Orleans.

Authorities say they still don’t know how Timothy Thompson IV died.

NOLA.com/The Times-Picayune reports (http://bit.ly/2ax9v42) reports that the boy’s grandmother reported him missing on July 5. After the body was discovered a day later, the boy’s parents, 21-year-old Gabrielle Whittington and 21-year-old Onterio Thompson, were arrested on charges of unlawful disposal of human remains and obstruction of justice.

Whittington has been released from jail on bond. Thompson remains in jail. It’s unclear if either has an attorney.
