Surveillance video shows lead-up to officer-involved shootings that injured 2 'celebrating' with gunfire on Milwaukee's south side

MILWAUKEE (CBS 58) -- A 22-year-old Greenfield man and a 17-year-old Milwaukee teenager are in the hospital after two officer-involved shootings happened just minutes apart Friday night on Milwaukee's south side.

Milwaukee police said officers were near Cesar Chávez and Scott attempting to break up a large crowd that was engaging in "reckless behavior" during Cinco de Mayo festivities.

That's when several people began firing shots around 11 p.m. in the area.

One officer came upon an armed suspect who was firing shots near 15th and Scott. The officer gave instructions to drop the gun and then fired at the suspect hitting him.

The suspect, the 22-year-old Greenfield man, was taken to a local hospital for treatment of non-fatal injuries. His handgun was recovered.

The officer involved in this shooting is a 33-year-old man with over seven years of service. He was placed on administrative duty as is usual in an officer-involved shooting.

The Milwaukee Police Department Homicide Unit is investigating this shooting because the injury to the man was not life-threatening.

CBS 58 obtained surveillance video from a nearby business that shows the crowd starting to run, after the first shots were fired. 

Just moments later, the video shows someone wearing red, who was later identified as the teenager, stop running and start firing into the air as well. 

Milwaukee police said an officer also gave instructions to drop the gun before shooting the suspect. 

Cell phone footage provided to CBS 58 from the 17-year-old's sister shows an officer firing at him multiple times before he fell to the ground. 

Officials report the teenager is suffering from serious injuries but is now stable. His handgun was also recovered. 

The officer involved in this shooting is a 40-year-old man with over seven years of service. He was placed on administrative duty as is usual in an officer-involved shooting.

The Milwaukee Area Investigative Team is investigating this shooting because it was first believed the suspect’s injuries were life-threatening.

The Wauwatosa Police Department is the lead agency in this investigation.

One witness who lives nearby told CBS 58's Ellie Nakamoto-White he was walking to his local gas station when he first heard the chaos.

“I saw people running and then just down the block people started firing gunshots," said Christopher Velez. “I didn’t know how to react, just felt traumatized since then.”

Velez said his fight or flight instincts kicked in and he took off running toward his house. Now, he and his family are considering leaving the area.

“They want to move from this neighborhood because they’ve recently noticed the crime started getting worse," Velez said. 

If anyone has any information about this shooting, please contact the Wauwatosa Police Department at (414) 471-8430.

According to police, there were no other reported injuries.

Police warn celebrating with gunfire is unacceptable.

They further state many shots were fired in the area, including some by fully automatic weapons.

They say they are thankful no other people, including their officers, were hurt by this gunfire.
