Police later spotted him with what appeared to be blood on his shirt, triggering a chase before officers took him into custody after he resisted arrest.

Investigators also recovered a backpack, cellphone and a second bag allegedly containing medical supplies tied to the defendant.

His defense team claims Arielle Konig was the aggressor and that he struck her with a rock in self-defense.

Gerhardt Konig has pleaded not guilty to all charges.
