of the Mexican federal police on the case, but they distrusted the state and municipal officials. They suspected that because state and local authorities were acting slowly and not sharing enough information, Kilroy's murderers had insiders within their ranks. On 26 March, the case was highlighted on national television in the crime show America's Most Wanted. This gave the case nationwide attention and generated several phone calls and letters with people giving clues on Kilroy's whereabouts. However, the police stated that none of the leads generated were solid enough to pursue. A few days later, Kilroy's parents returned to Santa Fe. Santa Fe residents raised money through garage sales and car washes to help Kilroy's family continue their search.

Police determined that the driver of the truck was Serafín Hernandez Garcia, the nephew of a local drug lord whose operations were based around the ranch area. But instead of arresting Hernandez Garcia, the police decided to continue gathering more evidence on the suspected criminal activities at the ranch and the organized crime members involved with the Hernández family.

On 9 April, they returned with several other policemen and arrested Hernandez Garcia, his uncle Elio Hernandez Rivera, cult members David Serna Valdez and Sergio Martínez Salinas, and Domingo Reyes Bustamante, the ranch's caretaker. While in custody, the detainees were very relaxed. They were sent to jail while
