Police still mum on investigation in alleged hate crime, 7 weeks later

Ed Treleven | Wisconsin State Journal 6 hrs ago

Seven weeks after a biracial woman told police she had been sprayed with lighter fluid by a group of white men and then set on fire, police and the woman’s family say the investigation into the incident continues.

But little information about the June 24 incident has been released as the Madison police and the FBI continue to investigate. Madison police spokesman Joel DeSpain said Wednesday that he regularly checks with the lead detective on the case, along with the department’s Violent Crimes Unit, and said it is still an active investigation.

“There is nothing new to release at this time,” DeSpain said. …

In the meantime, police have not released any surveillance camera images, as they did in other recent cases that led to arrests in the June 24 attack on state Sen. Tim Carpenter, D-Milwaukee, and in the arrest of Marquon Clark, 26, of Madison, a “person of interest” in the firebombing of the City-County Building, which happened the same night. Police have also released images of other persons of interest in the CCB incident.
