HAMPTON, Va. (WAVY) — Defense attorneys have requested a psychological evaluation for the Hampton mother charged in the death of her toddler.

Julia Tomlin is charged with 2nd-degree murder, felony child neglect and concealment of a dead body after her 2-year-old son Noah’s body was found at a steam plant in Hampton last summer, days after Tomlin reported him missing.

Tomlin’s trial was originally set to begin on Monday. The judge will set a new trial date after the evaluation is performed on May 20 at 9 a.m.

In a January hearing, Hampton Commonwealth’s Anton Bell said he has around 30 witnesses who plan to testify at Tomlin’s trial. An autopsy revealed Noah died of multiple blunt force trauma injuries, and Bell says he believes the child was tortured.
