During the trial in 2007, the "biggest criminal trial in Bakersfield in decades", prosecutors emphasized Brothers' past marriage difficulties. Joanie Harper previously divorced him in 2000, but the couple remarried in
Las Vegas in 2003. Brothers was also known to have extramarital affairs, and further compromised his case by lying while on the witness stand. According to Lisa Green, a Kern County deputy district attorney, Brothers killed his family because they were a financial burden and he lied on the stand 41 or more times. On May 15, 2007, Brothers was convicted of the first-degree murders of his five family members after jurors heard testimony from 137 witnesses. Brothers is believed to have used a .22-caliber gun and "a stabbing weapon". His conviction carried the special circumstance of multiple murder. On May 29, 2007, the jury returned a sentence of death. According to sheriff's department spokesman Sgt. Ed Komin, detention deputies found that Brothers had hid handmade handcuff keys in his hair and had placed his leg restraints on one leg, which rendered them ineffective. He was returned to Lerdo Jail under additional security measures. ==Sentence==
