Sexual assault, beating case awaiting trial
Dustin L. Sperb, 21, Janesville, is charged with felony first-degree sexual assault and felony aggravated battery in the attack of Sandra L. Cole, 47, a former resident of the mobile home park. Sperb is scheduled to stand trial Aug. 23 in Rock County Court.
Cole remained in a coma in Mercy Hospital in Janesville for weeks after the assault, officials said, and she was later moved to Milwaukee for special treatment. Cole could understand people and answer questions with one word in August.
According to the criminal complaint:
Sperb was drinking alcohol at a bonfire in the mobile home park on the night of the attack, and witnesses say he was wearing a Yankees baseball cap.
Witnesses told investigators Sperb left the fire for a few hours. Sperb told detectives he walked away and passed out.
Cole’s blood was found on the T-shirt that Sperb wore that night. He also is likely the contributor to a DNA mixture found on Cole’s body.
A New York Yankees baseball cap also was found in Cole’s home.
Cole was unconscious and partially nude when she was found the next day.
A nurse at Mercy Hospital in Janesville evaluated Cole and found signs of sexual assault.
Sperb remains in the Rock County Jail on $40,000 cash bond.
