After more than two decades since the murder of David A. Vanderzee in Kenosha County, authorities have finally made arrests in the cold case. Roxanna L. Collins, formerly Vanderzee, of McHenry, Illinois, was detained last Wednesday, facing charges including First Degree Intentional Homicide; As a Party to a Crime; Use of a Dangerous Weapon. She is being held in the McHenry County Jail on a $75,000 cash bond, while awaiting extradition to Wisconsin. The Kenosha County Sheriff's Office, in a press release available on their website, confirmed the arrest and her current custody status.

John J. Viskocil of Genoa City, Wisconsin, was also arrested on the same day as Collins with parallel charges. His arrest warrant included First Degree Intentional Homicide; As a Party to a Crime; Use of a Dangerous Weapon. Viskocil is presently being held on a $500,000 cash bond at the Kenosha County Jail. The apprehension of both suspects has been attributed to the sustained, meticulous detective work that persisted to reexamine the cold case.

The Kenosha County District Attorney's office played a significant role in providing a fresh review, leading to the development of new leads in the longstanding murder case. The collaborative efforts between McHenry County, Illinois, Sheriff's Office and Wisconsin authorities were highlighted as an exemplary model of multi-jurisdictional operations geared towards enhancing community safety.

The Kenosha County Sheriff’s Office stressed their commitment "to protecting our community members and holding criminals accountable for their actions." Authorities took the opportunity to also extend gratitude to the Illinois officials who assisted in apprehending Collins.
