Jeffrey James "Jeff" Weise (August 8, 1988 – March 21, 2005) was an Ojibwe Native American adolescent, and a student at Red Lake Senior High School in Red Lake, Minnesota. He murdered nine people and wounded five others in a shooting spree on March 21, 2005, in the Red Lake Indian Reservation located in northwest Minnesota. Weise first murdered his grandfather and grandfather's girlfriend at his trailer home in Red Lake, an unarmed security guard, a teacher and five students at Red Lake Senior High School. The shooting ended when Weise committed suicide.

Jeffrey James Weise was born in Minneapolis, Minnesota, the only child to 21-year-old Daryl Allen Lussier, Jr. and 17-year-old Joanne Elizabeth Weise. His parents were an unmarried couple from the Red Lake Indian Reservation in Red Lake, Minnesota, who had separated before he was born. In November 1988, Joanne was forced by her parents to place her three-month-old son in the care of his father in Red Lake. In June 1991, when he was two years old, Jeff was reclaimed by his mother in the Minneapolis-Saint Paul area. His mother was alleged to be a violent alcoholic, who would physically and emotionally abuse her first born son.

John Dean "Jeff" Cooper (May 10, 1920 – September 25, 2006) was recognized as the father of what is commonly known as "the Modern Technique" of handgun shooting, and one of the 20th century's foremost international experts on the use and history of small arms.

Born John Dean Cooper, but known to his friends as "Jeff", Cooper graduated from Stanford University with a bachelor's degree in political science. He received a regular commission in the United States Marine Corps in September 1941. During World War II he served in the Pacific on the USS Pennsylvania. By the end of the war he had been promoted to major. Feeling his career prospects were limited by his lack of infantry experience, he resigned his commission in 1949. He returned to active duty during the Korean War, was involved in irregular warfare, and was promoted to Lieutenant Colonel. After the Korean war the Marine Corps declined his application to remain on active duty. In the mid-1960s, he received a master's degree in history from the University of California, Riverside.

Jeffrey Scott "Jeff" Buckley (November 17, 1966 – May 29, 1997), raised as Scotty Moorhead, was an American singer-songwriter and guitarist. He was the son of Tim Buckley, also a musician. After a decade as a guitarist-for-hire in Los Angeles, Buckley amassed a following in the early 1990s by playing cover songs at venues in Manhattan's East Village, such as Sin-é, gradually focusing more on his own material. After rebuffing much interest from record labels and his father's manager Herb Cohen, he signed with Columbia, recruited a band, and recorded what would be his only studio album, Grace.

Over the following two years, the band toured widely to promote the album, including concerts in the U.S., Europe, Japan and Australia. In 1996, they stopped touring and made sporadic attempts to record his second album in New York with Tom Verlaine as producer. In 1997, Buckley moved to Memphis, Tennessee, to resume work on the album, to be titled My Sweetheart the Drunk, recording many four-track demos while also playing weekly solo shows at a local venue. While awaiting the arrival of his band from New York, he drowned during a spontaneous evening swim — fully clothed — in the Wolf River, when he was caught in the wake of a passing boat. His body was found on June 4, 1997.
