Sidney Schiltz, 42, a male White/Caucasian from Sheridan, Illinois, died on July 17, 2025, after he and another victim, Melissa Vissman, were found inside a rural home that had been set on fire in the early morning hours. Deputies and the LaSalle County Coroner responded to a residence on North 42nd Road, where both victims were discovered after reports of gunshots and then a blaze at the same address. Authorities identified Sidney Schiltz at the scene and opened a homicide investigation while autopsies were scheduled for the following day.
Investigators said the sequence began just after 1 a.m., when 911 callers reported shots at the home; minutes later, a fire engulfed the residence. Two other people inside survived, one with injuries from shrapnel, and later told officials about the moments before and after the gunfire. According to prosecutors and witness statements, the assailant was searching for money, drugs, and a gun in a safe, and after the shooting, the house was set ablaze in an apparent attempt to destroy evidence.
Following an hours-long manhunt across LaSalle County on July 18, law enforcement arrested 45-year-old Ronald W. Martin Jr. He was found hiding on property owned by his family and taken into custody without incident. Prosecutors charged him with six counts of first-degree murder in the killings of Sidney Schiltz, 42, and Melissa Vissman, and a hearing was set to determine pretrial detention. Officials also said that two eyewitnesses were present during the shooting and that a firearm believed to have been used was recovered.
Court documents and statements from authorities described that both victims were shot multiple times, with Sidney Schiltz struck in the back of the head. Investigators additionally questioned a man related to the suspect on suspicion of aiding and abetting after the killings; he was later released the same day when prosecutors said there was insufficient evidence to charge him. As the investigation continued, officials noted that the fire complicated evidence collection, but the case against the accused proceeded with multiple murder counts tied to the death of Sidney Schiltz, 42.
Public records of the death list Sidney Schiltz, age 42, lost to gun violence in Sheridan on July 17, 2025, and case listings identify him as male and White/Caucasian.
