Horry County Police arrested a mom after they say she left her 3 1/2 year-old and four-month-old children home alone while she went to a bar.

Saturday night around 11:30 p.m., Kathleen Salling's 3 1/2 year old son was found running down Highway 90 Saturday night wearing only his pajama shirt and a diaper. A couple from Calabash, NC was driving on the highway and nearly hit the boy.

They stopped and picked him up and called police.

Police drove through the area neighborhoods looking for the boy's home. They found a door open to a home on Carriage Lake Drive near Little River. Inside they found photos of the 3 1/2 year old, as well as a four-month-old baby asleep in a crib.

Police used phone numbers found in the home and contacted the children's grandparents who gave them the mother's cell phone number.

Police say they reached Salling on her cell and asked if she knew why they were calling. According to the incident report, Salling replied, "Yes, because I left my children home alone."

The incident report also says Salling admitted to having gone out to help a friend and then stopping at a bar to have a few drinks. Police believe she was gone from the home for more than two hours.

The Department of Social Services has custody of the two children. Salling is charged with Unlawful Neglect of a Child.
