(Scroll down for video) It was a very tragic day when two sister and their teenage babysitter drowned while having fun in a swimming pool.

Police are still investigating the deaths of 3-year-old Azucena Gandarilla, her sister Amaya Gandarilla, 6, and their 17-year-old babysitter, Joo Lee.

Police said that foul play was not suspected, and the tragic accident occurred in Pueblo, Colorado.

The babysitter took the children to the swimming pool, which is located at a mobile home apartment complex.

Neighbors said that there are usually many people in the swimming pool, looking out for one another, as there are no lifeguards on duty.

However, for some reason, nobody was at the swimming pool at the time that the children drowned. However, there were people in the area and they called for help.

Emergency workers administered CPR, but they were unable to save the sisters or their babysitter.
