A Butler police officer put out a fire early this morning in the kitchen of a second-floor apartment where the tenant apparently left while cooking food on the stove, authorities said.

No one was injured in the fire at the three-apartment building at 114 W. Brady St., owned by Cunningham Shanor.

The initial 911 call at 6:12 a.m. reported possible entrapment.

Patrolman Nicholas Shulik was first there and made it up the steps and into the apartment that was filling up with smoke.

“It turned out to be a grease fire,” said police Lt. Chad Rensel. “(Shulik) put a lid on the (frying) pan and put out the fire.”

Rensel and other officers also made a check of the building to make sure everyone was safe and accounted for, police said.

Butler firefighters arrived to ensure the fire was out.

D.J. Hudak and Jill Kennedy were still half asleep in the living room of their third-floor apartment when they realized there was fire coming from the apartment below theirs.

“It smelled like burnt toast,” Hudak said. “Then smoke started coming up through the bathroom.”

They were getting out just as the first fire trucks made it there.

The tenant on the first floor was already aware of the fire and apparently tried to alert the woman where it started.

Police believe he opened the door and called out for her. When Shulik got there the door was opened and the smoke detectors were going off. By then, whatever was cooking in the pan was burned black.

The electric stove was “melted up,” Shulik said.

The destroyed appliance was apparently the extent of the damage.

Even as fire crews were packing up to leave about 6:40 p.m., the second-floor tenant, a woman in her 60s, had still not shown up.
