A shooting at a southern US university left three people dead and a biology professor denied a job promotion has been charged with murder.
After opening fire at a faculty meeting, Amy Bishop (photo, from bbc.co.uk) was apprehended outside a science building at the University of Alabama in Huntsville campus.
If convicted, officials said she could face the death penalty. Reports said her husband was also being questioned.
The shooting happened after Prof Bishop found out she had been denied academic tenure, which guarantees job security, reported local media in Huntsville.
The three person killed were the head of department and two other professors, said Ray Garner, the University spokesman. No students were harmed in the incident.
Two of the three injured, also biology department members, are said to be in a critical condition in hospital. The third was reportedly in a “fair” condition.
The Huntsville campus in northern Alabama has about 7,500 students.
Prof Bishop is a neurobiologist who studied at Harvard University and had joined the biology faculty as an assistant professor in 2003.
History of shootings
In recent years, there were several fatal shooting attacks on US educational sites, most of which have been carried out by students, amid the country’s widespread debate about gun control.
The most serious occurred in April 2007 at Virginia Tech University, where a student killed 32 people before turning the gun on himself.
In 1999, 13 people were gunned down by two teenagers at Columbine school, Colorado,who then killed themselves.
Several shootings have already been reported around the US in the first six weeks of this year alone.
Eight people were killed last month in the southern state of Virginia. A man surrendered to authorities after a massive manhunt in the woods near the historic town of Appomattox, during which he opened fire at a helicopter aiding the search.
In early January, a disgruntled employee at a Missouri plant of a Swiss power company went on the rampage shooting dead three people and wounding five others. The bloody shooting is believed to have been triggered by a dispute with the ABB company over his pension funds. The employee also killed himself.
