LORI HACKING CASE Police review letter, surveillance images

A police affidavit reveals other items taken.
SALT LAKE CITY (AP) -- A letter found in the apartment of a missing Salt Lake City woman suggests she was having marital problems with her husband, who is now accused of killing her.
"I hate coming home from work because it hurts to be home in our apartment," said the letter, excerpts of which were included in a police document released Wednesday.
"I can't imagine life with you if things don't change. I got someone I don't know I want to spend the rest of my life with unless changes are made."
The document does not explicitly say who wrote the letter, but Mark Hacking's first name was written on the outside of the folded note. The warrant does not say whether the note was typed or handwritten.
Other items
In a 42-page affidavit, police revealed dozens of items seized from the couple's apartment, their vehicles and Mark Hacking's workplace locker. Other items taken include a hunting knife, a piece of bloodstained carpet, a personal computer and a stained pillowcase retrieved from a trash bin outside the apartment.
Hacking has been charged with murder, accused of shooting his wife, Lori, after an argument provoked by her discovery that he had been lying about his college education and plans to enroll at a medical school.
Prosecutors filed court documents detailing Hacking's confession to the slaying, made to his brothers when they visited him in a psychiatric ward.
An executive with a security-camera company said Wednesday that police were reviewing surveillance images from a hospital where they believe Mark Hacking dumped his wife's body in a trash container.
Cameras' images
Justin Harryman, a vice president of FutureTech, said his company helped investigators review images taken by 16 motion-triggered video cameras at and around the University of Utah Neuropsychiatric Institute, where Hacking worked as an orderly.
It took police three hours to methodically review images from just one of the cameras, Harryman said.
"It's hard to say if it's him," said Harryman, who refused to elaborate.
It was not immediately clear what the person on tape was seen doing.
