The teen accused of shooting and killing two protesters and injuring a third on Tuesday in Kenosha, Wisconsin, opened fire after a protester threw a plastic bag at him, a criminal complaint obtained by The Daily Beast said.

Kyle Rittenhouse, who had expressed support for "Blue Lives Matter" and President Donald Trump, was charged on Thursday with five felony counts over the deaths of Joseph Rosenbaum and Anthony Huber and the injury of Gaige Grosskreutz.

The charges include first-degree intentional homicide and first-degree reckless homicide, as well as a misdemeanor charge of possession of a deadly weapon.

The 17-year-old had traveled up to Kenosha from his home in Antioch, Illinois, and told a reporter for the conservative outlet the Daily Caller that he was there to protect local businesses from looting.

Kenosha has been the center of regular protests since a police officer on Sunday shot Jacob Blake, a Black man, at least seven times in the back.

According to The Daily Beast, the criminal complaint said Rittenhouse was walking down a street in Kenosha at about 11:45 p.m. alongside the Daily Caller reporter when Rosenbaum approached and tried to "engage" Rittenhouse, who was armed with a rifle.

Investigators said videos they reviewed showed that Rosenbaum, who appeared to be unarmed, chased Rittenhouse as he ran across a parking lot and threw something at him.

"The object does not hit [Rittenhouse] and a second video shows, based on where the object landed, that it was a plastic bag," the complaint said, according to The Daily Beast.

Shortly after, the complaint said, a loud bang can be heard and a man shouts "F--- you!" Another four shots can be heard, and Rosenbaum falls to the ground, it said.

The Daily Caller reporter told investigators that he didn't hear the two exchange words but that he thought Rosenbaum was trying to grab Rittenhouse's gun when the teen fired.

The Milwaukee Medical Examiner's Office said Rosenbaum died of multiple gunshot wounds in his right groin, left hand, left thigh, and back, The Daily Beast reported.

The criminal complaint said that after shooting Rosenbaum, Rittenhouse made a phone call and could be heard saying, "I just killed somebody."

The complaint said protesters started chasing him, with some yelling "Beat him up!" and "Get him! Get that dude!"

It said several people tried to grab Rittenhouse's gun, including Huber, who the medical examiner said was fatally shot in the chest.

The complaint said that Grosskreutz, who appeared to be holding a handgun, was shot in the arm as he approached the teen. People close to Grosskreutz told the Chicago Sun-Times that he would require surgery.

Rittenhouse was taken into custody on Wednesday in Illinois. Because he is a minor, he is being held at a juvenile facility in Vernon Hills, ABC 7 Chicago reported.
