Excerpts from abc7chicago.com:

A fourth suspect has been arrested in connection with the shooting death of retired Chicago Fire Lt. Dwain Williams earlier last month.

Chicago Police Superintendent David Brown tweeted Friday that an individual was arrested on a separate warrant in Pennsylvania by the FBI and is currently being held on a $2 million murder warrant. Chicago police are seeking his extradition to the city.

Devin Barron, 20, of Lynwood was charged with one count of first-degree murder, one count of unlawful use of a weapon on a person with a loaded firearm, both felonies, as well as one misdemeanor charge of possession of cannabis more than 10-30 grams, one count of being a fugitive from justice with an out of state warrant, and two counts of issuance of warrant earlier this week in connection with Williams’ death. Barron was taken into custody by the Great Lakes Regional Fugitive Task Force Saturday morning around 10 a.m. in Lansing, Ill. He was due in bond court in Chicago Monday.

Dwain Johnson, 18, and a 15-year-old boy who has not been identified by name have also been charged in the shooting.

Family, friends and a community said a final goodbye to Lt. Dwain Williams last weekend.
