Narrative:

Received taxi instructions to runway 15R via taxiway a from gate. While I was looking at ACARS screen for weight and balance data, the captain left taxiway a and crossed runway 4/22. I looked up just as we were clearing runway and advised the captain of his mistake. I don't believe runway 4/22 was in use that evening. See diagram on other side. I take equal responsibility for this for not closely monitoring taxi path at a busy, confusing airport at night.
