SECTION 1: THE OFFICIAL CASE RECORD (VERIFIED FACTS)
Official Case Date December 5, 1982 (ID'd December 4, 2020)
Discovery / Last Seen Location Escatawpa River & Interstate 10, Moss Point, MS
Demographic Profile Caucasian Female Toddler, 18 Months Old (2'6", 25 lbs)
Anthropological Age Estimate 18 Months Old (DOB: June 1, 1981)
Primary Investigating Agency Jackson County Sheriff's Office & Othram Inc.
Forensic Identifiers Available Forensic-Grade Genome Sequencing (FGGS), Pink Checked Dress, Gwendolyn Clemons Mystery

On the chilly morning of Sunday, December 5, 1982, a commercial truck driver crossing the Interstate 10 bridge over the Escatawpa River in Moss Point, Jackson County, Mississippi, looked down into the marsh grass and spotted a tiny body floating in the water. For thirty-eight years, the toddler was mourned across the Gulf Coast as "Delta Dawn."

Discovery, Autopsy & Highway Sightings

The victim was an 18-month-old female toddler with blond strawberry hair and brown eyes, measuring 2 feet 6 inches tall and weighing 25 pounds. She was dressed in a pink-and-white checked dress with an embroidered flower on the chest, a disposable diaper, and white socks. An autopsy confirmed that water was present in her lungs, proving she was alive when she entered the river and had drowned.

Two nights earlier, on December 3, 1982, multiple motorists on Interstate 10 reported seeing a distressed young woman in her early twenties carrying an infant in her arms, walking in a daze along the shoulder near the Escatawpa bridge in pouring rain. Later that night, a motorist saw a female body lying in the river current, but marine search-and-rescue teams were unable to locate an adult decedent.

The Othram Genomics Resolution: Alisha Ann Heinrich

In 2019, Jackson County Sheriff Mike Ezell and investigator Matthew Hoggatt partnered with Othram Inc. Othram's genomic team built a comprehensive SNP profile from the child's degraded skeletal remains and traced genetic kin to Joplin, Missouri.

On December 4, 2020—exactly thirty-eight years after she was recovered—authorities announced that Delta Dawn was 18-month-old Alisha Ann Heinrich. Detectives learned that in late November 1982, Alisha's 23-year-old mother, Gwendolyn Mae Clemons, had left her hometown of Joplin with Alisha and an adult male companion, intending to start a new life in Florida.

While Alisha's identity has been restored, Gwendolyn Mae Clemons has never been seen or heard from again. Investigators believe Gwendolyn also met with foul play along the Gulf Coast highway, and Jackson County detectives are actively investigating her companion's movements.
