At about 9:45 a.m., the Janesville Police Department, with the assistance of the Department of Criminal Investigations (DCI), executed a search warrant in the 400 block of North Oakhill Avenue. The suspect, David Hoyle, age 68, was identified during the investigation and was taken into custody at the residence.

At about 11:30 a.m., a second search warrant was executed in the 2000 block of Taylor Court. The suspect, Marzette Conner, age 24, was identified during the investigation and was taken into custody at the residence.
