Police Ask for Public’s Help to Capture “Unstable” Gunman

The "mentally unstable" gunman who shot and killed a construction worker, shot a farmer and fled in a truck is still at large.

Now Indiana police are asking for the public's help in finding the cold-blooded killer whose motives are still unclear.

"Some one out there has to know who this man is," a Lake County Sheriff's Roy Dominguez said at a Thursday morning press conference.

He announced the creation of a bi-state joint police task force to find the man. Dominguez said it will be a 24/7 operation.

The department has recieved about 100 tips on the killer, but cops need more info. They released an updated composite sketch of the suspect.

On Tuesday the unknown gunman shot and killed 45-year-old rolando Alonso of Hammond, Indiana after asking the construction worker about some unused wood at a construction site there. It was his second day on the job.

The man also shot 19-year-old Josh Garza, of Dyer. Garza was moved from Advocate Christ Medical Center in Oak Lawn, Ill., because a reporter found his room and authorities feared for his safety after the incidend.

His aunt, Kristina Garza, said he's coming along.

"He's recovering one day at a time," she said.

Said gunman then traveled 13 miles to the residence of farmer Keith Dahl and shot him, police said. Ballistics technicians observed similar characteristics from bullets used at both incidents.

The gunman remains at-large and should be considered armed and dangerous, authorities said. He is believed to be driving a light colored 1995-1998 Chevy Cheyenne.

Residents are on edge.

"Oh, yeah, everybody that I've talked to that has guns have [loaded theirs]," said one Beecher resident.

Investigators from Will County, Ill., and Lake County, Ind., said they're comparing bullets from the victims to try and determine if the gunman had more than one weapon.

They said they're also being flooded by tips and leads from residents. Many of them are unfounded. But it's not deterring authorities, who are working around-the-clock to put the gunman behind bars.

The suspect appears to be in his 40s and was last seen wearing a light green windbreaker, a ball cap, light-colored jeans and brown work boots.

"I think he's still here. I really do. I think he's hiding out," said Beecher resident Larry Whisenang. "There's so many places out here to hide."
