The HOA Murders
Two old men who bullied neighbors in their homeowner's association (HOA) are found shot dead in the Arizona desert near the Mexico border. Pima County Sheriff's detectives Juan Caldera and Junior Collins work the case. Drug and gun smugglers, Minutemen and aggrieved members of the HOA are on the suspect list. When more neighbors die from poisoning after a potluck, the focus narrows to the HOA.
