A Lockport man allegedly set a mattress on fire at his home after arguing with his mother over household chores, police said.
Shortly before 10 p.m. Friday, officers were dispatched to the 700 block of East Ninth Street after receiving a report of a structure fire, said Lockport Deputy Police Chief Ron Huff.
When the officers arrived, they found a man and his mother outside the burning residence, Huff said.
During the ensuing investigation, the officers and Lockport Township Fire Protection District arson investigators determined that Edward Biller, 37, had intentionally set the fire following an argument with his mother, Huff said.
The argument was over household chores, he said.
The fire was started on a mattress in a second-story bedroom, Huff said.
Firefighters contained blaze inside the bedroom, Huff said. Smoke and water damage spread throughout the rest of the residence, he said.
Biller was arrested booked into the Will County jail on probable cause of arson.
Biller appeared in court Saturday morning and his bond was set at $1 million.
Biller was scheduled to return to court Tuesday afternoon, at which time prosecutors will decide whether to file formal charges, and if they do, a hearing will be held on his bond.
Biller pleaded guilty to arson in June 2017 and was sentenced to three years in prison after spending more than eight months in the county jail, court records show.
