A young mother’s three children were left to fend for themselves in a Butler home filling with smoke last week after the woman passed out from drinking alcohol with the oven turned on, city police said.

Police Wednesday arrested 24-year-old Samantha L. McConnell on three felony counts of child endangerment.

District Judge Sue Haggerty arraigned McConnell on the charges and remanded her to Butler County Prison on $3,000 bail.

Butler County Children and Youth Services caseworkers notified police about 4:10 p.m. June 23 during a routine welfare check on the defendant’s children, ages 3, 6 and 7, at the family’s home in the 300 block of Mitchell Avenue.

“When CYS arrived,” according to court documents, “they found the house to be filled with smoke and the children seemingly unsupervised.”

The caseworkers got the children out and turned off the oven, police said. The food that had been cooking in the oven was burned.

Butler Patrolman David Villotti said officers found McConnell unresponsive and lying on the bathroom floor. It took the officers about two minutes to wake her.

The defendant, who appeared intoxicated, admitted to “drinking vodka throughout the day,” documents said.

She told police that she did not know her children were home.

The children currently are staying with family members.

“She repeatedly told officers that she was taking a nap while she waited for her children to get home,” Villotti said in his criminal complaint.

He also noted that McConnell has two prior arrests for child endangerment in the past year.

Most recently, Butler police arrested her Jan. 23 when she showed up, allegedly drunk, at the Broad Street Elementary School with her youngest child.

She admitted consuming vodka before walking to the school, court documents said.

McConnell was charged with child endangerment, a felony, and public drunkenness, a summary. That case is pending in Butler County Court.
