In a shocking Thanksgiving incident, an Illinois man found himself behind bars after allegedly setting fire to his family’s residence following a fierce disagreement, according to local authorities.

The accused, 21-year-old Erik J. Crump, now faces charges of aggravated arson and residential arson linked to the fiery episode.

The Lake County Sheriff’s Office reported that deputies responded to a call around 7:30 p.m. on Thursday. The call came from a home located in the 40100 block of North Lone Oak Road in Beach Park, where a heated argument had been reported.

Family members expressed their frustration to the deputies, claiming that Crump had been provoking others within the household. Despite the tension, officers determined that no criminal act had been committed at that moment.

In an effort to calm the situation, deputies managed to deescalate the confrontation, and Crump agreed to leave the family premises for the rest of the night.

However, the evening took a grim turn, ultimately leading to Crump’s arrest and the serious charges he faces today.

About an hour later, deputies returned to the home for reports of a fire.

When firefighters arrived, they saw a man matching Crump’s description standing near the roadway armed with a knife, before he fled.

Deputies set up a perimeter, and a sheriff’s K9 tracked his scent to a dead-end, indicating he may have left in a vehicle.

Crump was later located at a storage facility in the 39400 block of North Lewis Avenue and taken into custody without incident.

Detectives determined that Crump had been told after the earlier argument that he would be kicked out of the home. He allegedly returned, used an accelerant to ignite his bedroom, and fled as the fire spread, causing major damage.

The family then noticed smoke filling the home and immediately evacuated.

“It’s nothing short of a blessing that nobody was injured or killed in this senseless act,” Sheriff John D. Idleburg said in a statement. “While families across Lake County were sitting down for Thanksgiving, our dispatchers were answering the call, and our deputies were out responding to them.”

“Our team, along with our fire service partners, responded within minutes, secured the area, helped ensure the fire was extinguished, and took this individual into custody before anyone else was put at risk,” he continued. “I am incredibly proud of their professionalism and their commitment to keeping our community safe every hour of every day.”

The Lake County State’s Attorney’s Office, after reviewing the circumstances of the incident, approved the aggravated arson and residential arson charges.
