A Northwest Side man hired as a caregiver for an elderly, disabled man faces a felony abuse charge after police in Milton, Wis., found the disabled man in unclean conditions and suffering from suspicious injuries, police said.

Syren Bolderdene, 35, of the 4000 block of North St. Louis Avenue, was charged Thursday with felony abuse of an at-risk person in the village of about 5,000 people less than 10 miles northeast of Janesville, according to police and court records.

Bolderdene was held overnight in the Rock County Jail, but in a hearing this afternoon, Rock County Judge James P. Daley ordered he be allowed to sign a $5,000 personal recognizance bond, according to the the county court clerk’s office.

The victim, a 76-year-old Milton man, was being treated at Mercy Milton Medical Center in Milton, police said in a news release.

Bolderdene had called 911 about 11 a.m. Thursday to request help after the victim, a 76-year-old man, fell out of bed, and Bolderdene could not get him back up, according to a news release from Milton police. Police did not disclose the victim’s address.

Police found the victim had been left in a soiled diaper and bedclothes saturated with his own urine and feces. Investigators believe he had been left that way for at least 24 hours.

The victim had what police said were suspicious fractures, bruising and scratches.

Bolderdene’s next court date is June 18, according to the clerk’s office.
