The yellow crime scene tape wrapped around an apartment unit on Sylvia Street in Christopher on Saturday morning.
And investigators with the Illinois State Police, were busy going in and out of the front door of Apartment B.
Shortly before 1:00 a.m., the Christopher Police Department received a 911-dispatch from the Franklin County Sheriff's Office.
The caller told the dispatcher that there was an unresponsive male on the floor, inside the apartment.
When officers from Christopher and Ziegler arrived on the scene along with an EMS team they tried to resuscitate the male.
But, they were unable to do so. And he was pronounced dead by the Franklin County Coroner.
Now the police say they are investigating his death as suspicious.
"He wasn't shot or stabbed from what my officers could see when they got inside the apartment," Christopher Chief of Police Bill Southerd said.
The chief called in the Illinois State Police at that point to handle the investigation into the death.
The victim's sister Towana Young recalls how her brother, 40-year-old Ronald "Scott" Maceri, spent his final moments leading up to his death on Saturday morning.
"He was here with my mother yesterday. He was helping her clean the house," Young said. "She had told him not to go back over there to that place. And he went anyway. My mother told me not even a week ago that she was afraid he's going to get hurt over there real bad. And he did."
Young says that her brother and the woman who lived in the apartment had been seeing each other on and off for the past six months.
And that he was always willing to help anyone any way he could.
"He was a good brother and a good son. He loved his mother. We loved him, he was so good hearted, just a very good hearted guy. He's going to be missed a lot."
Illinois State Police removed several bags of evidence from inside the apartment on Saturday morning. And they examined some of the wooden furniture that was piled into a burn pile in the back yard of the building.
"I just wish this hadn't happened. And there needs to be justice over it," Young said. "Because no one deserves to die like that."
The Franklin County Coroner has scheduled an autopsy to determine the cause of death.
