RALEIGH, N.C. — A young Raleigh mother appeared lifeless and blood was everywhere when her sister found her lying face-down on her stomach in her bedroom last Friday afternoon, according to a portion of a 911 recording released Monday afternoon.

"I think my sister's dead," a frantic Meredith Fisher tells the Wake County 911 dispatcher.

Authorities said blunt force trauma killed Michelle Marie Young, 29, but they haven't released any further information. Young was about 20 weeks pregnant with her second child, authorities said.

Investigators said that Young's husband, Jason Young, who was out of town, had asked Fisher to go to the house to pick up a fax for him. When she arrived at the scene, "the dog was freaking out" and "the place does not look like what it normally looks like," she says in the 911 call.

She also tells the dispatcher she found Young's 2-year-old daughter, who authorities said was unharmed, at her mother's side.

"There's like blood footprints all over the house, like her daughter's little footprints," Fisher says in the five-minute recording, in which she tries to quiet the child and keep her in a room while she talks to authorities.

Fisher can also be heard asking the child if she knew what happened, if her mother had fallen and if anyone had been in the home.

Authorities said there was no sign of forced entry at the house, located in the Enchanted Oaks subdivision at 5108 Birchleaf Drive, and authorities said the slaying doesn't appear to be a random act of violence.

Meanwhile on Monday, Wake County investigators continued combing the house for evidence. They also conducted interviews with people who knew Michelle Young.

"I feel like we're going in the right direction," Wake County Sheriff Donnie Harrison said, "and it's just going to take time and good police work."

Authorities said they believe Young had company until about 10:30 p.m. Thursday. Jason Young had left town Thursday night for a business trip and was at his parents' home in Brevard when his sister-in-law found the body Friday afternoon, authorities said.

Harrison said Monday that investigators had not yet interviewed Jason Young.

"We probably will be talking to him pretty quickly," he said. "He was talked to just briefly Friday afternoon, and that's all."

Investigators confirmed Monday afternoon that they had impounded his car and its contents. People close to the case told WRAL that he is speaking with an attorney.

Investigators, however, have not named any suspects and have asked that anyone who might have seen suspicious activity or unfamiliar vehicles on Birchleaf Drive between midnight and 6 a.m. Friday to call the Wake County Sheriff's Office at 919-856-6800.

"I have no compassion for whoever did this. I'm just hoping we can make a speedy arrest," Harrison said, adding that he was glad Young's daughter was not harmed.

"I think it's a tragedy that anyone would do this to start with, but with a child in the house like this, it just makes me mad. I'm going to be honest with you," he said.
