In a series of emails and interviews with News 8, Bremner said the witness now believes the woman he saw was Nina's sister, Dina Shacknai.
"The witness sent me a picture of Dina and said it was Dina," according to Bremner, who said the witness was riding a bicycle by the home at approximately 10:20 p.m. on July 12.
"He was going by and saw somebody with a large, black bag trying to get in the front door and looking around and going to the back of the house," Bremner said. "She was 40 to 50 years, 5'5", 170 to 190 lbs., long dark hair; wearing a black and white striped short sleeve shirt," said Bremner.
"He is positive it (was) Dina and she was acting very suspiciously," Bremner wrote. "He has seen subsequent news reports that said Nina was out front and he said that's not the person he saw."
