The Cupertino quarry shooting occurred on October 5, 2011, in a quarry in Cupertino, California. This shooting spree left three people dead and six others injured. Shortly thereafter, the shooter, Shareef Allman, shot a woman whose car he was attempting to carjack.[1] It was initially believed that Allman was shot to death by Santa Clara County sheriff's deputies in Sunnyvale on October 6, but an autopsy revealed that Allman had committed suicide.[2][3]

The shooter, Shareef Allman, was 47 years old and worked at the quarry.[4] Allman was an employee of Lehigh Hanson's Permanente Cement Plant, the site of the quarry in the hills to the west of Cupertino. He had worked at the plant for 15 years.
Allman married singer Qwen Mejia in July 1989. She is also known as Valeri Allman.[5] Their marriage was marred by a series of violent incidents perpetrated by Allman against his wife, according to court documents. Mejia obtained a restraining order against Allman in 1992 and divorced him.
Allman fathered a daughter, Lashae Allman, who was born in 1993. Lashae Allman's mother was a woman other than Qwen Mejia.
Shareef Allman wrote a novel, Amazing Grace, about a fictional victim of domestic abuse who overcame her tribulations with the help of God.
The three men killed are: Mark Muñoz, 59, of San Jose; John Vallejos, 51, of San Jose; and Manuel Guadalupe Piñon, 48, of Newman. Among the seven people injured were Jesse Vallejos and Mike Ambrosio.[6][7]
Allman's rampage also caused a variety of schools, such as Lawson Middle School, and Stratford Middle School to have lockdowns. Lynbrook High School was put into "Code Blue."
