The two owners of a new children’s summer camp in Larissa, central Greece, and a swimming pool attendant on Saturday faced a prosecutor on charges of manslaughter through neglect, after two 9-year-old girls drowned in the camp’s main pool. Police who were called to the camp on Friday afternoon said that several children had been in the pool at the time and that the alert was raised when one of the girls was seen floating on the surface. According to some of the children, the two girls, reportedly best friends, had been competing to see who could hold her breath the longest. It was unclear whether a lifeguard had been on duty at the time of the drownings, which occurred on the camp’s first day of operation. Meanwhile, another 9-year-old girl was in a critical condition in a Hania hospital after losing consciousness while in a hotel swimming pool.
