Some area residents say the shooting comes as no surprise because there have been others within a two block radius over the years. Others say it still comes as a shock.

“I’m not that familiar with it. I grew up in a small town in Wisconsin, so it’s always new to me,” resident Dustin Waltz said.

Police say they’ve stepped up patrols in the area, especially on weekends with the bars are closing.

“We’ve known that and we have accounted for that. We have a numerous number of officers in the area,” Detective John White said. “We anticipate that there’s going to be large crowds and we staff for that purpose.”

Police say Rosario-Lopez’s mug shot won’t be released just yet because they need all of the witnesses to be able to identify him in a lineup first. He does have a criminal record that includes a long list of felony charges that are all drug related.
