Elementary, my dear Watson

I'm going to help out the Marietta, Georgia police with this one:

Police said Hutcherson and Brohm -- friends since high school -- were drinking at a bar Saturday night and left after Brohm said he felt sick.

Brohm, 23, apparently was leaning out of the window when Hutcherson hit the support wire about a mile and a half from the bar, but police did not know why.

By using my powers of deduction, I'm going to guess that Brohm thought he was going to throw up, and that's why he was leaning out the window, minutes after leaving a bar where he complained he felt sick, but hey, what do I know?
