FOX 2 and Crime Stoppers are working to solve a four-year-old mystery. A Brownstown Township woman vanished the same day her house went up in flames. Her husband has long been suspected, but her family is still desperate for answers.
A snapshot of an inferno at the Brownstown Township home of Lizzie Mae Collier-Sweet was taken the same the 49-year-old disappeared. It was January 8, 2007.
Despite an intense police investigation and countless tips, her body has never been found.
"My sister was almost six feet tall, almost 200 pounds. How does six foot tall, 200 pound woman just (vanish) off the face of the earth," said Louise Collier, the victim's sister.
Police believe Lizzie's husband, Roger Sweet, knows the answer, but he's never cooperated. He's currently locked up for life for the murder of his first wife, a death that was initially believed to be an accident, and for sexually abusing a mentally impaired teenager.
Investigators think Lizzie found out about the abuse and was going to turn him in before she died.
"He simply states that he doesn't know where she is, he had nothing to do with it," said Robert Grant with Brownstown Township police. "Somebody had to reach out to somebody. There had to be some conversations somewhere."
Police do believe Roger Sweet is responsible, but they don't think he acted alone. They still think someone out there has information that will solve this case.
Crime Stoppers is offering a $1,000 reward for information, and Lizzie's sister plans to visit Roger Sweet in prison to appeal to him herself.
"We know as a family that she's gone. All (we're) looking for is closure right now," Collier said.
After four long years, the family says they need those answers.
