A $10,000 reward is being offered for information leading to an arrest in the Dec. 2 shooting murder of a DuPage County-area activist on Chicago’s West Side.

Naperville resident Ronald L. Allen spent 40 years as an agent for Allstate Insurance Cos. Fellow agents, members of their families and other well-wishers went to work shortly after Allen’s death, amassing the reward money and offering it through the Community Action Network, or CAN.

"We, the friends of Ron Allen, managed to raise $10,000 for information that leads to the arrest and conviction" of those responsible for his death, CAN Executive Director Joseph C. Ziegler Jr. said Friday.

"At some point, somebody is going to talk or tell somebody something" about the shooting, said Ziegler, who owns an insurance agency. "And when they do, we hope that we’ll get some information" that leads to an arrest in the case, he said.

Chicago police are continuing their investigation into the slaying of Allen, 73, a married father of four from Naperville’s northwest side.

"There is no one in custody for that incident at this time," an email Friday from the Chicago Police Department’s office of news affairs stated. "The investigation is ongoing."

Keith Allen, one of Allen’s sons and an attorney based in Warrenville, said Friday police have not contacted the family recently to discuss the case or update them about it.

Ronald Allen was shot in his car in the 1300 block of North Laramie Avenue in Chicago’s Austin neighborhood after having spent the evening playing cards and socializing with friends. His insurance agency had been in Austin.

Allen, after retiring, founded the Unity Partnership outreach group, which aims to foster cooperation and goodwill between DuPage County law enforcement agencies and residents.

He also was a longtime parishioner of the DuPage African Methodist Episcopal Church at 4300 Yackley Ave. in Lisle, which hosted his funeral services Friday and Saturday.

An online obituary asked that monetary donations be made to the "Ron Allen Scholarship Fund," in care of the church.

In addition to Keith Allen, survivors include his wife, Carol J. Allen; his daughter, Vera Bass; and sons Mark Allen and Koryon Perfeet.

Witnesses to the shooting, or those who believe they have information about Allen’s death, can call CAN at 800-U TELL US, or 800-883-5587. All information will be kept confidential, according to a CAN news release.
