King was originally charged with just assault.

According to prosecutors, King allegedly bound Dobson’s hands and feet, struck him with an electrical cord and belt buckle, locked him outside on a patio in low temperatures, burned him with a hot oven rack and watched him starve, losing up to 20 pounds, all while he was in her care during three weeks in December.

Police responding to a 911 call at the Ritz Plaza building on West 48th Street on Jan. 8 found Myls burned, bruised, cut, emaciated and unconscious in the bathroom, prosecutors said. Dobson was pronounced dead at Roosevelt Hospital.

King initially told police she had put the boy on the bathroom counter and left the room briefly. Police said King told them Dobson fell and landed in the empty bathtub in her Midtown apartment.
