Shooter may have specifically targeted females
All but one student killed and three teachers were female.
Winnenden -- All but one of the nine students killed and seven injured in a German school massacre on Wednesday were female and the three slain teachers were also women, a local official said.
"It is noteworthy that primarily girls were killed -- eight girls and one boy ... The teachers killed were women," said Heribert Rech, interior minister of the southern state of Baden-Wuerttemberg where the slaughter took place.
"I don't want to speculate too much about this at this point ... The students sitting nearest the door were girls," he said.
Rech also said that police did not have "sufficient indications" on the possible motives of the 17-year-old killer, who shot himself in a firefight with police after a dramatic manhunt involving hundreds of officers.
As well as the 12 killed at the school, Kretschmer also killed three passers-by. Two police officers were also seriously injured.
The gunman, named as Tim Kretschmer, had been until last year a pupil at the secondary school where the bloodbath occurred, achieving "average" marks in his school-leaving certificate, Rech said.
He then enrolled in a course training to be a salesman. He also regularly worked out at the gym and belonged to a sports club, Rech said.
"He was described as reserved," he added.
