Teacher among the Oregon college victims of gunman Chris Harper-Mercer

A teacher and three high school graduates were among those shot dead at Oregon community college by a gunman armed with three pistols and a rifle, as well as five additional magazines.

Police released brief details of the nine people killed in the shock attack, who range in age from 18 to 67 and include three 18-year-olds.

Nine people are still being treated for injuries they suffered when Chris Harper-Mercer, whose father is reportedly English, opened fire at Umpqua Community College in Oregon on Thursday before dying in a shoot-out with police.

President Barack Obama is ordering that American flags be flown at half-mast in honour of the victims of the mass shooting at the college in Roseburg.

The authorities have identified the nine victims as 19-year-old Lucero Alcaraz, of Roseburg; 18-year-old Quinn Glen Cooper, of Roseburg; 59-year-old Kim Saltmarsh Dietz, of Roseburg; 18-year-old Lucas Eibel, of Roseburg; 67-year-old teacher Lawrence Levine, of Glide; 33-year-old Jason Dale Johnson, of Winston; 18-year-old Rebecka Ann Carnes, of Myrtle Creek; 44-year-old Sarena Dawn Moore, of Myrtle Creek; and 20-year-old Treven Taylor Anspach, of Sutherlin.

Mr Cooper, who was in his fourth day of college when he was shot, was described as "sweet and compassionate" in a family statement read out by police.

A statement from the family of Mr Johnson said he was "proud of himself" to have recently enrolled in college and had "finally found his path".

Mr Eibel had begun studyingchemistry and volunteered at a wildlife centre and animal shelter.

Two victims, including Trevor Anspach who was described as "larger than life", were part of the "immediate fire family", the local fire service said.
