While an AR-15-style rifle is a semi-automatic design, keep in mind that a gun does not have to be a rifle to be semi-automatic. Many handguns also are semi-automatics, as are numerous models of hunting rifles and shotguns. The killer in the 2007 Virginia Tech shootings killed 32 people with two semi-automatic handguns. 321

When the tank failure was found on March 4, University Hospitals said the loss was expected to be only 2,000 specimens, or nearly half of the tank's contents. Many families held out hope that their eggs or embryos might have been saved.That was not to be. University Hospitals delivered the news that all contents of the tank had been lost -- more than 4,000 eggs and embryos -- in a letter to the 950 families dated March 26."We are heartbroken to tell you that it's unlikely any are viable," the letter said, adding that the tank had been turned off by an unknown person."An alarm should have been sent and received. We don't know who turned off the remote alarm nor do we know how long it was off, but it appears to have been off for a period of time. We are still seeking those answers," the letter said.In an emailed statement, the tank's manufacturer, Custom Biogenic Systems, denied allegations that the tank malfunctioned and made it clear that the alarm system was not its responsibility."Based upon our initial investigation, we have concluded that our equipment did not malfunction. The early stages of our investigation into this unfortunate incident indicate it was the result of human error," the statement said, adding that the company "did not design, manufacture, install, control, or monitor the remote alarm system that was reportedly 'off' during the time of this incident."In its letter to the families, University Hospitals also said that the tank had been undergoing preventive maintenance, with advice from Custom Biogenic Systems, for several weeks before the temperature rose. The autofill mechanism had quit working, University Hospitals said, and employees were filling the tank by manually pouring in liquid nitrogen.The manufacturer had been working with the hospital on how to re-enable the autofill feature, Custom Biogenic Systems said, but it claims that hospital staff had stopped its "recommended practice at least several days before the incident." When employees began filling the tank from the top, the manufacturer said, they made a serious error."The tank is not designed to be filled by liquid nitrogen being 'poured into the top of the tank,' as UH admits it was doing in its letter. This is an incorrect fill method and will cause liquid nitrogen to come into contact with the stored samples."In addition, by pouring liquid nitrogen into the top, the manufacturer said, the employees bypassed the system that monitors the levels in the tank."Rather, the read-out measures the level of liquid nitrogen in the liquid nitrogen reservoir, which was bypassed by UH's use of the 'container filling' method," its statement said. 2665

Witnesses told 10News the impact caused the truck to flip so high into the air that it nearly hit traffic signals well above the street. The truck’s driver was ejected as the vehicle went airborne and landed on the pavement. 224

When they give that instruction, someone's able to follow it explicitly, quickly and obediently and what that does is saves lives, Baumann explained."It just opens up my eyes as to what a marine is, as to whatever preconception I had in my mind prior," Woodward said. "Not being lazy and being able to ask for help, the same reasons you fail in my class are the same reasons you'd fail here."The teachers hustled to the receiving room where drill instructors demanded they remove anything from their pockets, spit out gum, and read the rules on possession during bootcamp. 577
