KILLEEN - It's an hour from midnight, and the December air is cold and dry. Fallen leaves from an aged pecan tree crunch under the feet of Army Spc. Eric Jasinski. The parking lot at Under the Hood Cafe is dark, vaguely illuminated by the warm orange glow that emanates from Fort Hood into the foggy night sky. Light leaks out of curtained windows. Jasinski stoops to reach through the car window to embrace and reassure his mother, Laura Barrett, while his father, Michael, warms up the car. He kisses his fiancee, Robyn Schultz, and kisses a sleeping, bundled baby boy, 10-month-old Tristan. Both women struggle to hold back tears, troubled by what tomorrow might bring.
