Wisconsin police officials say the officer who fatally shot an armed man in Kenosha on Saturday was on his first day back at work after shooting another armed suspect earlier this month.
Aaron Siler, 26, was killed when he tried to evade arrest in his car, before crashing and using a weapon to confront officers who had chased him on foot, police said Monday.
Kenosha police Lt. Brad Hetlet identified the officer who fired the fatal shots as Pablo Torres.
"When the suspect was confronted by Officer Pablo Torres, the suspect armed himself with a weapon," Hetlet said. "Officer Torres fired his handgun striking and killing the suspect. There were citizen witnesses to the incident."
Police have not specified exactly what Siler was armed with when he was killed.
Torres was on his first day back at work after taking leave and receiving training following an incident on March 4 in which he shot a man who advanced on officers with knives, Hetlet said.
"The Kenosha Police Department understands the toll this incident has taken on the family, the community, the involved officers and their families, and the department," Hetlet said.
"These tragedies can be avoided if subjects would simply stop and follow the commands of the officers."
The state's Division of Criminal Investigation has launched an inquiry into the incident, Hetlet said.
It was the second fatal, officer-involved shooting in Wisconsin in just over a week, following the death of 19-year-old Tony Robinson on March 6.
Robinson was shot dead by Officer Matt Kenny in Madison after police responded to a call of a man behaving erratically.
Protests followed the death of the unarmed black teen, with university and high school students marching on the state capitol building.
