FORT MILL — A Fort Mill mother is charged with leaving her children alone in their apartment early Sunday after a neighbor found her 2-year-old son walking barefoot near an apartment complex parking lot and then discovered her 4-month-old daughter in a crib inside an empty home.

Colleen Louise Pellettiere, 26, faces two counts of unlawful neglect of a child. She is jailed at the York County Detention Center on a $10,000 bond.

Deputies were sent to Palmetto Place Apartments around midnight after receiving a call from Pellettiere's 38-year-old neighbor, who told deputies her boyfriend saw a 2-year-old boy walking barefoot near the complex's parking lot, according to a York County Sheriff's report. The woman came out of her apartment and asked the boy about his mother.

That's when he pointed towards an apartment with its front door wide open, the report states. When the neighbor walked inside, she found a 4-month-old girl in a crib. She told police that she couldn't find any adults or formula for the baby inside the apartment. The neighbor took the baby and boy back to her apartment, where she called police.

About an hour after police were on scene, Pellettiere returned to the apartment wearing a blue halter top and tight black pants, according to the report. Deputies also noticed a black stamp mark on the back of her right hand that may have been from a nightclub or pub.

Pellettiere, who police say "appeared to be agitated and unsettled," didn't give "just cause" for why she left her children home alone, the report states. The Department of Social Services arrived on scene and began interviewing Pellettiere. During the interview, she kicked the wall behind her.

She was escorted into a patrol car and taken to the Fort Mill Police Department, where she was booked before being taken to the York County Detention Center. Deputies found a can of alcohol with a straw sticking out of it in her car, along with a pair of blue high heel shoes with another shirt in her car.

DSS placed the children with a foster family in Lake Wylie. The children's father, police say, has a pending case with North Carolina's department of social services and was unable to take custody of them.
