Police have a lot of questions but not many answers after a late night stabbing.

Investigators are having a difficult time figuring out just what happened in that stabbing of a man around 11 p.m. Saturday.

They say they do know a woman lent her car to that man to go to the store, and when he returned he was stabbed and bleeding.

The woman took the man to Santa Rosa Children's Hospital, thinking it was a regular hospital.

EMS then transported the man to University Hospital.

The man could not tell police who had stabbed him or why.
