Lon Tomohisa Horiuchi (born June 9, 1954) is an American former Federal Bureau of Investigation (FBI) Hostage Rescue Team (HRT) sniper and former United States Army officer who was involved in the 1992 Ruby Ridge standoff and 1993 Waco siege. In 1997, Horiuchi was charged with manslaughter for killing Vicki Weaver at Ruby Ridge, but the charges were later dropped. Early life and education Horiuchi was born on June 9, 1954, in Hawaii as the son of a U.S. Army officer. He later attended the United States Military Academy at West Point, and graduated in 1976. He served as an infantry officer in the U.S. Army. Afterwards he joined the FBI, and by 1999 had been an FBI agent for at least 15 years. Ruby Ridge In 1992, while working at sniper position Sierra 4 for the FBI Hostage Rescue Team at Ruby Ridge, Horiuchi shot and killed unarmed Vicki Weaver, wounded her husband, Randy Weaver, and wounded family friend Kevin Harris. After his first shot hit and wounded Randy Weaver, Horiuchi fired a second shot at Harris as he retreated into a cabin. This shot wounded Harris and killed Vicki Weaver, who was standing in the doorway holding her 10-month-old child. Following the conclusion of the trial of Randy Weaver and Kevin Harris in 1993, the U.S. Department of Justice (DOJ) created a "Ruby Ridge Task Force" to investigate allegations made by Weaver's defense attorney Gerry Spence. On June 10, 1994, the Task Force delivered its 542-page report to the DOJ Office of Professional Responsibility. The Report stated: "With regard to the two shots fired on August 22, we concluded that the first shot met the standard of 'objective reasonableness' the Constitution requires for the legal use of deadly force but that the second shot did not satisfy that standard." The surviving members of the Weaver family received $3.1 million in 1995 to settle their civil suit brought against the U.S. government for wrongful deaths of Vicki Weaver and 14-year-old Samuel Weaver, who was killed the day before during an encounter with U.S. Marshals. In the out-of-court settlement, the government did not admit any wrongdoing. In a separate suit, Harris received a $380,000 settlement from the U.S. government in 2000. Manslaughter charge In 1997, Boundary County, Idaho Prosecutor Denise Woodbury, with the help of special prosecutor Stephen Yagman, charged Horiuchi in state court with involuntary manslaughter over his killing
