An Anne Arundel County teenager pleaded guilty Thursday to the murder of his five-year-old half-sister, according to state court records.

Police said Stephen Jarrod Davis II, now 19, fatally stabbed Anaya Jannah Abdul on Oct. 3, 2020. Davis fled after Abdul's death but was later apprehended in Ohio.

Davis' public defenders have sought for Davis' mental health to be evaluated. Davis' mother told police that he got along well with his sister and he was not violent before Abdul's death.

Davis will now stand trial in April to determine if he was criminally responsible or not, the equivalent of the insanity defense in Maryland.
