The cases against two mothers who drove into running water with their children last month have been dismissed.

The case against Edna K. Encinas, 29, was dismissed because the evidence presented to the Pima County Attorney’s Office was “insufficient to prove the charge beyond a reasonable doubt,” said Kellie Johnson, chief criminal deputy county attorney.

The case against Tiffany N. Sherman, 18, was dismissed to give the Pima County Sheriff’s Department more time to investigate, Johnson said.

Sherman was arrested on suspicion of child abuse on Sept. 6 after she called 911 about 11 a.m. to report she was stuck in a wash in a Buick sedan with her 1-month-old baby.

When deputies arrived, the car was partially submerged, and water was inside the vehicle.

Deputies rescued the mother and infant, and neither suffered any injuries.

Road closure signs were clearly visible and placed in the middle of the roadway, Deputy Tom Peine said at the time.

The baby was given to a grandmother, who arrived at the scene.

Encinas was arrested on suspicion of child abuse the following morning when a tow truck driver called 911 to report one of his customers had driven past road closure signs and gotten stuck at West Valencia Road and South Camino Verde.

The tow truck driver told the woman he could not get to her because of the road closure, Peine said at the time.

Deputies and Drexel Heights Fire District firefighters made their way to the vehicle and found the woman and three children, ages 2, 6 and 11.

The children were turned over to relatives.
