MILWAUKEE — As a photojournalist for TMJ4, I’ve covered this intersection countless times for car accidents. It’s an unmarked street, and once again, tragedy has struck. A local business captured the incident on surveillance footage, and the owner tells me the speeding on 76th Street is out of control.

A Milwaukee family is mourning after two sisters were hit by a speeding car at 76th and Mill Road on Saturday night. Surveillance video from a nearby business shows the sisters approaching the intersection just moments before being struck by the speeding vehicle. "It’s devastating," says local reckless driving activist Tracey Dent.

According to their mother, Talise and De-Lisha Dunmore were out celebrating a birthday when the unthinkable happened. The medical examiner reported that 20-year-old Talise was thrown 50 to 75 feet upon impact, suffering fatal injuries. De-Lisha was rushed to the hospital with serious but non-life-threatening injuries.

"What if a senior citizen was crossing the street? Look at this—" (points to a speeding car) "—and here’s another one. This is exactly what I’m talking about," says Dent. Community activist Tracey Dent has been tirelessly advocating for awareness about reckless driving in Milwaukee.
