Mom's Boyfriend Sets Christmas Tree On Fire, Toddler Injured

Police are looking for a possibly shirtless and shoeless man who set his girlfriend's Christmas tree on fire Sunday night, injuring the couple's 1-year-old boy.

About 8:30 p.m. Sunday, a woman's intoxicated boyfriend entered her home in the 4800 block of South Kolin Avenue and allegedly set her Christmas tree on fire after an argument, according to the Chicago Sun-Times. He then fled the residence.

Firefighters rescued the couple's 1-year-old son, bringing him down from the second floor by ladder, the Chicago Tribune reports. Other children in the residence were able to exit safely.

The man, who was not wearing a shirt or shoes, ran down the street and managed to avoid being captured by police, the Tribune reports.

He was not in police custody early Monday.

The boy was treated for smoke inhalation at Saint Anthony Hospital.
