Chicago shooter who killed three posted social media rants

CHICAGO (AP) – A man who police say killed three people and wounded four others during a series of shootings in and around Chicago posted nonsensical and expletive-laced videos in the days and hours leading up to the attacks.

Investigators on Sunday were trying to determine a motive for the Saturday afternoon attacks in which police say 32-year-old Jason Nightengale apparently chose his victims at random. Police killed Nightengale in a shootout just north of the city about four hours after authorities said he shot his first victim in the head in a South Side parking garage.

Those killed included a 30-year-old University of Chicago student from China named Yiran Fan, a 20-year-old man and a 46-year-old security guard. Wounded were a 77-year-old woman, an 81-year-old woman and a 15-year-old girl, according to Chicago Police Superintendent David Brown. Another woman was shot in the neck in Evanston, police in suburb said.

Authorities didn’t release many details about Nightengale, a Chicago man whose LinkedIn page listed work over the years as a janitor, security guard and forklift operator. But a series of disturbing videos posted to Facebook over two years under Nightengale’s middle name, Oliver, offered clues as to his state of mind.

In one posted on Thursday, Nightengale held a gun to the camera and muttered unintelligible statements as he appeared to be driving. A police official who spoke on condition of anonymity because he was not authorised to speak publicly about the investigation confirmed it was Nightengale in the video.
