Raleigh, N.C. — Home video of Michelle Young and her daughter, Cassidy, baking cookies in the kitchen reminds her family of happier times – a time before the pregnant, 29-year-old mother was found beaten to death in her Wake County home.

Cassidy, 2 at the time, was found next to her mother, unharmed, on the morning of Nov. 3, 2006. The case remains unsolved.

"It makes me very sad to know that Cassidy is going to grow up without her mother, her wonderful mother, who adored her," Young's mother, Linda Fisher, told WRAL in an exclusive interview earlier this month. (Watch the full interview with Fisher.)

Late Wednesday afternoon, Fisher shared exclusively with WRAL four home video clips never before made public to keep her daughter's memory, death and the fact there has been no arrest in the public eye.

The clips show Young interacting with her daughter. In one clip, Young is walking with Cassidy at MacArthur Airport in Islip, N.Y., on Long Island. In another, she's teaching her daughter to steer a toy Jeep.

And after speaking with investigators and prosecutors last week, Fisher said she is confident progress in the case will lead to an arrest.

She's not alone in the effort to keep the case alive.

"She was murdered in a violent, senseless way," said Kim Linder, who is part of a grassroots group dubbed "the Magnet Militia." "She was a beautiful, pregnant mother."

An autopsy revealed Young died of blunt-force trauma to the head after being hit at least 10 times. Several of her teeth were knocked out, her jaw was broken; she had bruises on both hands and injuries to her neck that showed her killer also tried to strangle her.

Wake County sheriff's investigators have made no arrests and have named no suspects, but they continue to say they are making progress in the case.

"There is a sense of frustration, but we have faith in Sheriff (Donnie) Harrison and in the investigators," Linder said.

Last month, the group distributed 2,500 magnets with a photo of Young and her husband, Jason Young.

The group includes people from all over the United States – some who were friends with Michelle Young and others, like Linder, who felt compelled to get involved. The group is planning other remembrances for Young, which might include something other than magnets.

"It deeply affected me to know that Cassidy is going to have to grow up without her mom," Linder said.

Information from search warrants indicate the the investigation has appeared to centered on Jason Young, although detectives have not called him a suspect.

Neither is the Magnet Militia.

"We would rather not comment one way or the other as to what we think his involvement is," Linder said. "Right now, we want the focus to stay on Michelle's case and whoever murdered her. We want them to be put in jail."
