One person was killed and six others were injured in a shooting Monday night at a Halloween party at a Kansas City, Kansas, home, police said.   

  Between 70 and 100 high school students gathered at the home when the shooting occurred, Kansas State Police Chief Carl Oakman said during a news conference, according to CNN affiliate KMBC.   

  The shooting was reported shortly after 9 p.m. when a group of uninvited guests were asked to leave the party, the chief said.  At least one person in the group began shooting into the crowd at the party, according to Oakman.   

  “The owners of the house asked them to leave.  As they left, they started shooting at the house.  I shoot at random,” Oakman said.   

  At least two of the injured are in critical condition, Oakman said.   

  Information about the party had been posted on social media and was “by invitation only,” Oakman noted.   

  The suspects were in a dark or gray SUV, Oakman added.   

  The police chief expressed his dismay at the violence, calling the shooting disturbing and unacceptable.   

  “These things in the community have to stop.  There are too many guns out there.  This was a high school party,” Oakman said.  “Everybody has guns now.  We have to be smarter than that.”   

  No arrests were made Monday night.
