Two children were pulled from Phoenix-area pools over the weekend, including a 4-year-old boy who remains in extremely critical condition. A 1-year-old girl later died after being pulled from a pool Saturday night. Phoenix fire officials say the incidents are a tragic reminder that drownings can happen quickly, even when adults are nearby. With excessive heat and a holiday weekend ahead, first responders are urging families to stay alert around water. Officials also pointed families to swim lessons, CPR classes, pool fence programs and other water safety resources.
