MERRILLVILLE, Ind. (CBS) – In light of the dropped murder charges against Lynwood police officer Brian Dorian for a two-state shooting spree, there is still a killer on the loose.

CBS 2’s Suzanne Le Mignot talked to investigators in Indiana about their search on Wednesday. Once again, residents there are concerned. They want the killer caught.

So does Lake County Sheriff Roy Dominguez. Dominguez says his department has never stopped looking for the shooter. Dominguez says they are still getting tips every day.

“I get them, our chief gets them, our detective bureau gets them, people who are comfortable with different police officers, we get them every day, all the time,” said Dominguez. “And we go through each one and we’re thankful for them.”

Dominguez says the public’s help can make the difference in law enforcement finding the man in the sketch. He’s responsible for killing one man and wounding another near Beecher, Ill.; then shooting another man in Lowell, Ind.

“We’ve sent evidence that we have retrieved to the Indiana state police crime lab for both scientific and forensic analysis,” said Dominguez. “Once we receive the report and the results of those examinations, then we’ll move forward.”

As for the charging and release of Brian Dorian in Will County, Dominguez said: “Having worked with them, I know they’re methodical about it, because their detectives and our detectives, we’re going through all the information. Ultimately, they make the decision based upon the facts and the evidence that they have, applying Illinois law to proceed forward.”

Those we spoke to, who call Indiana home, are very concerned the shooter is still on the loose.

“I just hope they catch him and I hope he doesn’t hurt anybody else along the way,” said Indiana resident Barbara Klumpe.

“I don’t like to have to lock up the windows in the house as much as you typically would, but in this day and age, unfortunately there are people out there where it requires that,” said Indiana resident Ryan Dykes.

“They say the shooter came and talked to somebody about honeybees or something simple, and I think it’s too bad that we’ve almost created a society where you can’t just speak to somebody and be friendly with people, or you might get shot. And that’s sad,” said Indiana resident Tracey Krueger.

Meantime, Sheriff Dominguez says the shooter was driving a light blue, or light colored 1995 to 1998 Chevy Cheyenne truck.
