"We're not taking this lightly," said Officer Steve Aponte with the San Jose Police Department. "We're taking this very seriously."
Aponte says that the ninth homicide happened Sunday morning around 11 on Vera Lane when they got a call from a loved one of the victim that a woman was injured.
"When officers arrived, they discovered an adult female victim who had sustained at least one stab wound," Aponte said. "That victim was pronounced deceased at the scene."
The suspect is still at large and they don't have a motive.

As for the tenth homicide, a double shooting, the few details available are also disturbing.
Police responded to the scene on 10th Street near San Jose State just after 3 a.m., Officer Aponte also commenting on that one.
"When (officers) arrived they located an adult female suffering from a non-life-threatening shooting injury," he said. "They discovered an adult male who also had a life-threatening injury."
First responders tried to perform lifesaving measures on that man but he eventually died, the woman is expected to survive.

Right now police are not saying anything about the relationship between the man and the woman, only that more information will be released at a later time and that the public is safe.
"We don't believe that there is a threat to the public," Aponte said, "There is no ongoing threat of some stranger going out there and committing these crimes."
