Prayers are in order for dozens of families in Thailand after a former police officer opened fire inside a daycare, killing at least 24 young children. In total, 37 people were killed and another 12 were wounded. The shooter took his own life after the attack. It's the deadliest mass shooting in Thailand's history. Most of the children who died were preschoolers. The gunman was reportedly fired from his position as a police officer months ago after being caught with drugs.
