Alisha Ann Heinrich, previously known as "Baby Jane" and "Delta Dawn", was a formerly unidentified American child murder victim whose body was found in Moss Point, Mississippi, in December 1982.

The child — aged approximately 18 months — was partially smothered before she was thrown alive from the eastbound Interstate 10 bridge into the Escatawpa River, where she ultimately drowned.

These eyewitness reports subsequently given to investigators would further be corroborated by accounts from a woman who had been monitoring CB radio conversations between truck drivers early in the morning of December 3, and who stated to investigators numerous truck drivers had been raising what she termed a "boatload of hell" regarding an obviously distressed woman walking along Interstate 10 with a barefoot, coatless female toddler in her arms and who had repeatedly refused any offers of assistance from passing vehicles.

This truck driver immediately reported his discovery to the Jackson County Sheriff's Office, and a sheriff's deputy immediately responded to the scene; finding no body floating in the general area of the river in which the body had been sighted, this deputy decided to continue the search, expanding the geographical search radius of the river as he did so.

Shortly thereafter, he discovered the body of a small blond-haired child lying partially submerged and face up in the weeds close to the bridge.

[11] Because the child's body had lain in the river for approximately 36 to 48 hours prior to her discovery, her eyes had clouded to such a degree that determining their precise color was very difficult, although it is believed they had been either blue or brown.

[11][n 4] Delta Dawn was buried in the Jackson County Cemetery following an hour-long service conducted at the Bethel Assembly Church in Pascagoula.

The primary means of paying for and conducting the child's funeral were donations by various local businesses and their employees,[13] and Delta Dawn was buried beneath a flat granite marker with a ceramic vase.

[14] This memorial service was organized by two Alabama women named Marjorie Brinker and Lynn Reuss, who have both stated they could not comprehend "why someone would throw a baby into the river like that.

[22] With advances in technology, several forensic facial reconstructions of the child were created in the years following the discovery of her body in ongoing efforts to identify her.

The National Center for Missing & Exploited Children also released two illustrations depicting potential likenesses as to how Delta Dawn may have physically appeared in her life; other forensic artists also produced their own renderings in efforts to discover her identity.

[7][6] On December 4, 2020, Jackson County Sheriff's Office announced the identification of Delta Dawn as 18-month-old Alisha Ann Heinrich of Joplin, Missouri.

[25][23] The circumstances surrounding Alisha's death, and the simultaneous disappearance of her mother, remain under active investigation by the Jackson County Sheriff's department.

"[23] Prior to the Jackson County Sheriff's Department's formal announcement of the identity of Delta Dawn as Alisha Ann Heinrich, the previously unknown woman accompanying the child upon the eastbound Interstate 10 bridge was theorized to have been responsible for her death in a suspected murder-suicide, although this theory is now in doubt.
