(Scroll down for video) A mother was arrested on a charge of manslaughter after her 6-year-old son killed his 2-week-old sister who was left alone with him in a hot car, according to police in Florida.

The Pinellas County Sheriff’s Office said that they have arrested 62-year-old Kathleen Marie Steele, after being accused of leaving her 2-week-old daughter named Kathleen alone with the 6-year-old boy and another 3-year-old child.

According to the police investigation, Steele went into a cellphone store on Monday, leaving her children alone in a hot car.

When Kathleen began to cry, the 6-year-old boy beat her. The children were left in the car for 30 minutes. When Steele returned to the car, the boy told Steele that Kathleen was injured, but she ignored him.

After arriving home, she called a neighbor who then called 911.

Police officers and paramedics who arrived at the scene, tried to revive the baby, but they were unsuccessful. While the paramedics were working on the baby, Steele put away groceries in the kitchen.

Steele was the biological mother of the baby. Steele was artificially inseminated with the sperm of her dead husband.

The 6-year-old boy is too young to be charged. Police said that the boy is extremely remorseful, saying that people sometimes make very bad mistakes.

The children were handed over to the custody of the state.
