Officer Ortega's son plays with a loaded gun, accidentally shooting his sister while his mother showers. Mister M, having seen the danger from afar, uses his powers of intangibility to enter the apartment -- seconds too late.

Surprisingly for a Marvel Knights book, there's no blood in the final image, which tilts at a Dutch angle as if the POV is reeling from shock.
