A registered sex offender from Dixmoor accused of breaking into a Joliet woman’s home and attempting to rape her was found not guilty Thursday by a Will County jury.

Kenneth R. Williams, 34, was acquitted on charges of home invasion, aggravated criminal sexual assault, residential burglary and possession of a weapon by a felon.

The jury reached its verdict after evidence at trial showed fingerprints lifted from the victim’s home did not match Williams, said his attorney, Paul Napolski.

DNA found in the victim’s underwear also did not match Williams. Napolski said.

“This is a perfect example of the criminal justice system working exactly how it should,” Napolski said. “After being incarcerated for 10 months, an innocent man was set free.”

Police said Williams broke into a home in the 1300 block of Cumberland Drive shortly before 9 p.m. Oct. 18, 2012, a point in time when the 27-year-old victim’s husband and son had left the house to return rented videos.

A minute after her husband left, the home alarm sounded, police said. The victim saw a man wearing a black bandanna, black long-sleeve shirt and dark jeans, approaching her and holding a steak knife, according to court records.

Police said the man held the knife to her throat and pushed her down before attempting to assault her.

The man stopped when she told him she was pregnant, court records show. She said she would not call police, and the man left. The victim then immediately called police.

She told officers she recognized Williams from a house down the street, and she picked him out of a photo lineup.

A police dog tracked a scent from the victim’s house down the street to the house where Williams was seen, court records say.

When Williams was 26, he sexually abused a 13-year-old girl in Kane County, according to state police records.
