CHICAGO – Federal authorities are asking for the public’s help to track down seven people accused of violent crimes, including murder and carjacking, now featured on a newly launched “Chicago Most Wanted” list.

What we know:

The FBI Chicago announced the list following “Operation Summer Heat,” a joint initiative with state, local, and federal partners that led to the capture of 25 suspects in mid-August. The operation ended without injuries to officers, suspects, or the public.

With that effort wrapped up, the FBI says their attention has turned to seven “violent fugitives” considered a threat to public safety. All are facing felony charges, and authorities say reward money is available for information leading to their capture.

According to the FBI, the fugitives are:

• Aron Barcenas – first-degree murder
• Julio Caesar Bernal – first-degree murder

• Nesta Gray – murder
• Gary Luellen – carjacking
• Joseph Matos – first-degree murder
• Giovanny Portillo – attempted first-degree murder, aggravated battery
• Antonio Stigler – murder

One more person, Calvin Hutchinson, who was also on the list for alleged murder, has already been arrested in Wisconsin.

What they’re saying:

“Together, we are signaling to criminals that there will be no refuge or safe haven from law enforcement’s reach,” FBI Chicago Field Office Special Agent in Charge Douglas DePodesta said.

Chicago Police Superintendent Larry Snelling also issued a statement, saying: “Partnership is the cornerstone of holding violent offenders accountable as we work to make our neighborhoods safer. As we work with fellow law enforcement on these criminal investigations, we are asking the public to come forward with any information they have to assist in the apprehension of these suspects.”
