- A woman who was stabbed 19 times in a Rochester high rise stairwell has died.

53 year old Doreen Hildebrandt died  Tuesday at Strong  Hospital.

Hildebrandt was injured at the Andrews Terrace apartment complex on St. Paul Street on Jan. 29.

The man charged in her death, 47-year-old Dennis McFadden, pleaded not guilty to attempted murder and assault charges.

Hildebrandt's death could mean more serious charges for McFadden, who is currently set to return to state Supreme Court next month.
