The Will County Sheriff's Office on Tuesday night released this sketch of the man who shot at least three people earlier in the day.
An "All Points Bulletin" remains in effect in the hunt for a man who left one man is dead and two others wounded between Illinois and Northwest Indiana Tuesday.
The gunman, driving a light-colored pickup, possibly a Chevy Cheyenne, pulled up to a house under construction at the corner of Stony Island Avenue and County Line Road in Beecher, Ill.
"The suspect was at the house twice. He had come one time to see if they were going to sell the residence. They were apparently rehabbing it. It was a burned-out residence. He then left and returned to the house and talked to them about some materials like paneling or plywood at which time he opened fire," said Will County Sheriff Paul Kaupas.
Dressed in a disheveled manner and unshaven, the man pulled out a handgun and shot a worker from Rich Construction outside the home before entering and shooting a second man. Rolando Alonso, 45, of Hammond, Ind., was killed.
Alonso's 19-year-old colleague, who the Northwest Indiana Times identified as Joshua Garza, of Dyer, Ind., was airlifted to Christ Medical Center in Oak Lawn, said Will County Sheriff's Department spokesman Pat Barry.
"[He's] not doing so well," Garza's friend told ABC 7. "Got shot in the head."
The third worker fled into a nearby cornfield and was unharmed, according to authorities. It's believed it was that third man who called 911.
The gunman then stole the construction workers' Gray Ford F-150 and drove 13 miles to Lowell, Ind., where he engaged in conversation with a farmer.
"He stopped the farmer and started talking about putting bees in the area. The farmer appeared to have some interest in having them on his property. The suspect wrote what we believed might be a fictitious name and phone number on a note, handed it to the farmer at which time he opened fire on the truck that the farmer was in," Kaupas explained.
The farmer, Keith Dahl, slumped over on his steering wheel and pretended to be dead, Det. Rob Martinez said late Tuesday. The gunman then stole Dahl's wallet before taking off.
Dahl then drove himself off the property, while injured, and pulled over to call 911 from his cell phone. He was listed in stable condition at St. Anthony's Hospital in Crown Point after being shot four times, the Gary Post-Tribune reported.
All five schools in the Tri-Creek School Corporation, in Lowell, were placed on lockdown following the shooting.
Authorities said they believe the gun used was either a Colt .38 or a .357 revolver.
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. He is to be considered armed and dangerous, authorities said.
