A police officer in Waukegan, Illinois, was fired after he shot and killed an unarmed black teenager and wounded the young man’s 20-year-old black girlfriend during a traffic stop earlier this week.
The unidentified officer was terminated from his job on Friday night for multiple policy and procedure violations, the Waukegan Police Department said in a statement, three days after the incident left 19-year-old Marcellis Stinnette dead and his girlfriend Tafarra Williams wounded.
Some 200 to 300 people were expected to hold a demonstration calling for justice on Saturday in the city of 85,000 people in Lake County about 72 km north of Chicago, according to Clyde McLemore, a local organiser.
Similar protests and marches against racism and police brutality have swept across the United States during the last six months following the 25 May killing of black man George Floyd, who died in police custody in Minneapolis.
Waukegan is 25 km south of Kenosha, Wisconsin, where sometimes violent protests erupted after a white police officer shot Jacob Blake, a Black man, in the back several times on 23 August.
According to Waukegan police, a Hispanic male officer was conducting a traffic stop on Tuesday night when he shot into the couple’s car because it went into reverse and he "feared for his safety". No firearm was found in the vehicle, the police said.
Mr Stinnette, who was the passenger in the vehicle, died, while Ms Williams was wounded in the abdomen and wrist, according to Satrese Stallworth, a relative of Mr Stinnette and a spokeswoman for the family.

Ms Williams remains in the hospital, the Waukegan Police Department said.
“We do not trust the police narrative in this case. We have seen over and over that the ‘official’ report when police kill black people is far too often missing or misrepresenting details,” Ms Williams’ attorney, Ben Crump, said in a statement.
The US Department of Justice has agreed to assist the Illinois State Police in its investigation.
