On Sunday, October 1, 2017, officers in Kankakee found 25-year-old Luis Antonio Martinez fatally wounded inside a home on the 1000 block of West Hickory Street. An autopsy determined he suffered at least one gunshot wound, and police opened a homicide investigation that became the city’s fifth killing that year.

Officials later said investigators had secured arrests in only one of the city’s murder cases by October 20 and stressed the investigation relied heavily on witnesses coming forward. No motive was released and no suspect description was publicly provided in the immediate aftermath. Family notices identify Martinez as born September 14, 1992, in Kankakee, the son of Manuel and Elba Martinez, who worked as an auto detailer at Unique Detailing.

Does anyone who knew Luis or who was in the West Hickory Street area on October 1 have information that could help?
