Vincent Brothers

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.

On September 27, 2007, the Superior Court Judge Michael Bush sentenced Brothers to death based upon the jury's verdict and ordered Brothers to pay restitution. He was later placed into the custody of the California Department of Corrections and placed on death row at San Quentin State Prison.

Brothers, who had months earlier married his wife for the second time, was convicted of killing her, their new baby, two toddlers and his mother-in-law on July 6, 2003. He attempted to create an alibi by flying to Columbus, Ohio under the pretext of visiting his brother. He drove his rental car to Bakersfield, murdered his family members, and returned to Ohio. Forensic analysis of the rental car showed insects native to states west of the Rocky Mountains and odometer readings that supported the round-trip to California. Brothers was convicted of first-degree murders with special circumstance of multiple murder and was ultimately sentenced to death.

Brothers first gained national attention after the July 6, 2003 deaths of his wife, Joanie (née Harper), his sons, Marques (four) and Marshall (six weeks), his daughter, Lyndsey (two), and his mother-in-law, Earnestine Harper. Earnestine (70) was a mother of five children and civil rights activist. Joanie (39) worked for the Bakersfield school system and was a division one basketball official. Vincent and Joanie married in 2000, but had the marriage annulled in September 2001 due to Brothers' infidelity. They remarried in January 2003 when Joanie was pregnant with their third child. Vincent moved out of the house in April 2003.

Joanie, her mother and the children were last seen at church on July 6, 2003, and their bodies were discovered on Tuesday, July 8 in what appeared to be a staged break-in. Brothers had turned himself in to authorities in North Carolina where he was visiting his mother, but was released after a few hours due to lack of evidence at that time. Brothers returned to Los Angeles on July 11, 2003. He did not attend the memorial service for his wife, children, and mother-in-law, but attended their funeral on Wednesday, July 16. Although considered the only suspect from the beginning, he was not arrested until April 2004.

Brothers had been married four times, was briefly incarcerated for spousal abuse, and has a surviving daughter, Margaret Kern Brothers, who was the daughter of his girlfriend while attending California State University Bakersfield. In 1988, Brothers was convicted of misdemeanor spousal abuse. He received a six-day jail sentence and was put on probation. He married for a second time in 1992 and the following year his wife sued for divorce claiming that he threatened to kill her and was violent. In 1996, Brothers sexually harassed a woman who worked at the school where he worked as vice principal. She claims that during a visit to his home he hit her and was dissuaded by the police from filing a formal complaint against a man considered a "respected community leader". During an investigation by the school, Brothers denied the allegations and was warned of the effect of such behavior on his career, but he was not formally disciplined.
