Halloween night saw real-life violence sweep across the country, as shootings impacted teenage partygoers and even children out the evening that traditionally has trick-or-treaters go door to door. 

In Kansas City, Kansas, at least eight people were shot, including one fatally, at a private house party Monday night. 

When some unknown people arrived at the residence located in the 1600 block of South 50th Street and were asked to leave, the suspects opened fire before they fled the scene, Kansas City Police Chief Karl Oakman said, according to KMBC. 

The gunfire erupted around 9:07 p.m., reportedly while between 70 and 100 people, many of whom were high school age, were attending the party.

No arrests were immediately announced. When officers responded to the shots fired call, they discovered a deceased party on the scene from an apparent gunshot, and several others injured were transported to area hospitals, police said in a press release.

At least two of the others wounded were reportedly in critical condition. 

"This is very unfortunate. This stuff in the community has to stop. There's far too many guns out here. This was a party with high-school-age students. Like I said, everyone has guns now. We need to be smarter than this," Oakman said. "It's disturbing. It's unacceptable the number of people who are out here with guns. Regardless of what the situation is, we need to figure out how to manage our anger. Shooting people, taking the lives of people is not the answer. I mean, it's just ridiculous. We have to figure out how to resolve conflict in a peaceful way."

Police said the incident is under investigation by the KCKPD Major Case Unit. Anyone with information on this case is urged to call the Crime Stoppers TIPS hotline at 816-474-TIPS (8477). All tips remain anonymous and may qualify for a cash reward.

Meanwhile, a drive-by shooting on a Chicago street corner left up to 14 people wounded and in various conditions between critical and non-life threatening.

According to street camera video, preliminarily, investigators believe a single vehicle pulled up to the corner of California Avenue and Polk Street in East Garfield Park and at least two shooters shot randomly into the crowd at about 9: 30 p.m. 

The incident was over after a matter of just three seconds, Brown said.
