but he managed to grab his pistol under the counter and fire three shots wildly before dying. After that the murderers turned their attention to Myrtle, who had five gold teeth. First, one bandit shot Myrtle in the neck to stop her screaming, then knocked out her gold teeth with his pistol. She was then shot a second time in the head and killed. Frank's daughter Elizabeth was also grazed in the arm, but other than that the three young girls were left unharmed. The Mexicans left after they emptied the safe and destroyed the telephone. They then rode out of town yelling and firing their guns in the air. When the Mexicans were gone the Pearson girls fled eight miles away to the nearest neighbor. This time when authorities were called for an ambulance was sent from Nogales, which tended to Elizabeth's wounds. Meanwhile, a large posse of citizens and lawmen began searching the surrounding desert. A United States Army biplane from the garrison at Nogales was also dispatched to participate in the search and it became the first aircraft to be used for a manhunt in the history of Arizona. A $5,000 bounty, dead or alive, was also authorized for each of the seven Mexicans, partly due to the fact that the gang was suspected of being responsible for the first robbery. July 13, 1922 A few months later, after the manhunt had ended unsuccessfully, the authorities received news that two men in a Sonora cantina had bragged about being responsible for robbing the Ruby Mercantile. American police investigated the claim, but it wasn't until April 1922 that any arrests were made. By chance, an Arizona deputy sheriff overheard a conversation between the bartender and a customer at a cantina in Sasabe, Sonora; the bartender was trying to sell five gold teeth he had acquired sometime earlier by an outlaw named Manuel Martinez. When the deputy saw the teeth, he was sure they belonged to Myrtle so he bought them and took them back to the United States. Martinez was known for associating with a Mexican named Placidio Silvas, who lived near Oro Blanco, so the two were arrested and put on trial for murder in May 1922. Both were found guilty of murder by the court of Santa Cruz County. Martinez was sentenced to death by hanging and Silvas received a life sentence to be served at
