"This kind of violence is too intimate. I would think there is a more primary relationship in this situation because of the in-your-face violence," said Berrill, who said it's likely the killer had scouted out the building before committing the crime. "A boyfriend or a husband of a patient wouldn't have been as angry — they like to make threats more."
The killer was caught on the building's surveillance cameras and was seen entering the main entrance rolling one suitcase and carrying another. He was spotted about an hour later exiting through a basement door. Police describe him as a balding, middle-age man clad in a three-quarter-length green coat, knit cap and gloves.
