Alex Michael Bullerman, 18, of Waterloo, Iowa, was shot and killed in Cedar Falls in the early morning hours of Saturday, November 11, 2017. The shooting occurred in the College Hill commercial district near the University of Northern Iowa. Witnesses heard several shots in the 2300 block of Olive Street around 12:45 a.m., and officers found Bullerman in the backyard of an apartment building with a gunshot wound to the stomach. He was taken to UnityPoint Health-Allen Hospital in Waterloo, where he died; his organs were later recovered for donation.

Police say the shooting began after an altercation in a parking lot and appears not to have been random. Cedar Falls Police Chief Jeff Olson said Bullerman and another wounded man were known to be gang members. About an hour later, 18-year-old Dylan James Gehrke arrived at a hospital with a gunshot wound to his lower leg; he was treated and released. A multi-agency investigation followed and authorities sought help identifying a woman seen nearby. No arrests have been publicly announced.

Did anyone in the College Hill area that night see the woman or other details that could help investigators?
