According to officers, they performed a pursuit intervention technique (PIT) and the chase ended when the suspect's vehicle left the road and hit a tree in the 3200 block of S. 25th St, south of W. Oklahoma Ave.
The driver of the vehicle, a 25-year-old West Allis man, was killed. The officer, a 29-year-old with five years of experience, was uninjured.
This is the third high-speed chase Greenfield Police have been involved in over the last month.
She says the neighborhood has quite a few families with young children and she's grateful the tree was what stopped the chase instead of someone's home, putting children's lives at risk.
"What if it ran into my house?" Janners said. "My daughter's room is right there. She's in the front and we're upstairs. I don't know. It is scary."
Police say the Oak Creek police department is leading the investigation as part of the Milwaukee Area Investigative Team and is being assisted by member agencies as well as the Wisconsin State Patrol. A state law created in 2013 requires an outside agency to investigate whenever an 'officer-involved death' occurs.
