After Elda was reported missing, Gray participated in the search efforts, which raised suspicions among law enforcement.
Investigators observed that the pattern on Gray's shoes matched footprints found at the crime scene.
Under questioning, Gray led deputies to a culvert near the Colorado River, where Elda's body was discovered.
Internal examination revealed mud in the girl’s mouth, windpipe, and air sacs in the lungs.
Due to Deressa being known to frequently visit Gray's apartment to play with his cats, he was seen as a high priority suspect.
The police found him at the Colonel Dixie Hamburger restaurant on Highway 90, where his "live-in" girlfriend worked.
En route, it was decided that a statement should be taken from Gray and, after giving him the Miranda warnings, he was taken to the police station.

He was pronounced dead, twelve minutes after the pellets were released, by the doctor who could hear his heart through the stethoscope, die" according to a testimony by Dr.
[13] The decision to clear the room was sharply criticized by Dennis Balske, Gray's attorney.
"Jimmy Lee Gray died banging his head against a steel pole in the gas chamber while reporters counted his moans (eleven, not nearly enough according to the Associated Press)".
Traystman further testified that the lethal-gas method is sufficiently painful that it is disfavored in the scientific community as a way of putting animals to sleep.
