right now. did you have any sense of what it was? i had no idea what i was going to walk into. what he walked into was a nightmare beyond dreaming. there was his father in full blown panic and lying on the floor in a puddle of blood was his mother. and the rookie firefighter for an instant to his internal regret froze. if i would ve come on in that situation now, i would immediately started cpr. that was a great deal of blood. so for somebody to live through that, that much blood, i didn t think that it was going to happen. i believed i had just missed her couple of press. minutes later, mps arrived, and karen duenas was pronounced dead. the cause? multiple stab wounds and a gash in her chest. not long after that, the young detective arrived. a year under his belt as an
