DETROIT, Mich. -- A Detroit family wants answers after their loved one was found frozen to death on a city street.

Family members said 48-year-old Herman Chaney had mental problems and suffered from seizures.

The family said Chaney was discharged from Harper Hospital in Detroit on New Year's Eve and two days later he was found dead several miles away on Longwood Road near Woodward Avenue wearing a hospital gown and bracelet, a T-shirt and shorts.

The medical examiner's office said he froze to death.

Now his family has claimed the hospital is responsible

The hospital said records show Chaney checked into the emergency room at about 6:30 p.m. Monday, New Year's Eve.

A hospital spokeswoman said when the hospital last saw Chaney, he was alive, and there is surveillance video, showing him walking out of the hospital fully clothed.

The hospital said it has never sent anyone out on the street, particularly in the winter time.

The hospital also said Chaney signed himself out, and was discharged at about 8:30 p.m.

Hospital officials said he sat in the waiting room for about an hour and at 9:30 p.m., he walked out.

His family is upset the hospital never notified a family member he was being released, because he was a mentally ill patient.

They have hired an attorney to try and figure out what happened.

The family is also upset about the woman who found him lying in the middle of the roadway and called 911 early in the morning New Year's Day.

Detroit EMS claimed it responded, and did not find him in the road.

The woman went back to sleep and the next morning called EMS again.

EMS said they found Chaney the second time around on Longwood, but he was dead.

Chaney's family said it should not have taken that long to find him.
