A wake will be held Friday for the suburban couple that police said was killed by their own son.
Services for James and Diva Davis, of Plainfield, will be held at Johnson's Funeral Home on Chicago's West Side beginning at 4 p.m.
A funeral for the couple was scheduled to take place Saturday in Broadview.
James Davis Sr. was a part-time police officer in the village of Bellwood, officials said. A military veteran, he grew up in the area and was "like a pillar of the community," Mayor Andrew Harvey said.
Authorities said their son, James Eric Davis Jr., fatally shot them in his dorm room at Central Michigan University last Friday. He was captured early Saturday after a 16-hour manhunt in Mount Pleasant, Michigan.
He faces murder and gun charges and was ordered held on $3 million bail. James Eric Davis Jr. was taken to a hospital after his arrest and moved to the Isabella County jail on Wednesday.
The Davis family released a statement Tuesday to let James Eric Davis Jr. know "he has not been abandoned."
"In this very difficult time, the Davis family wants to express their love and support for Eric Junior whom they love and for him to know that he has not been abandoned," a release from an attorney on behalf of the family read. "Further, they want it known that Eric Junior is their main focus."
"They would also like to thank the friends and coworkers of Sergeant Davis and Mrs. Davis for all of the prayers and condolences that they have extended," the statement continued.
