Vincent Brothers (born May 31, 1962) is a convicted American mass murderer and the former vice principal of John C. Fremont Elementary School in Bakersfield, California. Brothers holds a Master's degree in education from California State University Bakersfield and a Bachelor's degree from Norfolk State University.
Brothers first gained national attention after the July 6, 2003 death of his wife, Joanie (née Harper), his sons, Marques and Marshall, his daughter, Lyndsey, and his mother-in-law, Earnestine Harper. Although considered a suspect from the beginning, he was not arrested until April 2004. Because of the high media attention surrounding the case, his trial was postponed until February 2007.
During the trial, 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.
On May 15, 2007, Brothers was convicted of the murders after jurors viewed 1,100 exhibits and 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 verdict of death.
