i remember steven lloyd shouting at them. >> i said ventilate him, ventilate him. >> they said i can'tiversal precautions. >> now more time ticks away. you can see a rescuer carrying a plastic bag with the all-important breathing gear, only now on the way down to the river. >> the man needed to be ventilated. i really thought this guy could have been saved. i really did. we really tried. >> by the time philadelphia rescue crews get him up from the riverbank into a local hospital, it's too late. matthew beaufort is dead. no one will ever know for sure whether he could have been saved. garrett couples says he doesn't blame the crowd or the police for not jumping in, if they weren't properly trained but he says it's hard to believe, with so many authorities on the scene, that none of them knew how to make a water rescue. >> i mean, it's, it doesn't make sense to me that you have fire rescue within two blocks, marine rescue within two miles, and none of them are trained in water rescue. to me, that is, i mean, that's unspeakable. >> after the incident, the victim's family files a complaint
