A teen from Maryland was arrested in Springfield, Ohio, after he allegedly took life of his 5-year-old half sister, then ran away.

Stephen Davis, 17, was captured on Saturday morning & charged with first-degree murder.

Cops were called to a Pasadena home around 8 a.m. on Saturday & discovered Anaya Jannah Abdul dead from quite a few sharp wounds, authorities said.

Investigators are still looking for a motive & it’s unclear how they came to suspect Davis, but officials said proof recovered from the home identified him as the prime suspect.

Davis led cops on a high-speed chase through Springfield before being taken into custody after a 20-mile pursuit.
